Refer to the circle to the right.
a. Find the circumference of the circle. use 3 as the estimate of π.
b. Find the circumference of the circle using 3.14 for π.
c. Another estimate of π is 3.14159. Find the circumference using this estimate.
d. What do you notice about the estimate used for π and the circumference of the circle?
Answer and explain how you got to your answer to get brainliest
Answer:
a. If π = 3 => C = 10 x 3 = 30
b. if π = 3.14 => C = 10 x 3.14 = 31.4
c. if π = 3.14159 => C = 10 x 3.14159 = 31.4159
d. using the whole number of π makes the calculation easier but using the π with more decimals will make the result more accurate.
Step-by-step explanation:
Diameter = 10 => radius = 10/2 = 5
Circumference: C = 2πr = 2π(5) = 10π
a. If π = 3 => C = 10 x 3 = 30
b. if π = 3.14 => C = 10 x 3.14 = 31.4
c. if π = 3.14159 => C = 10 x 3.14159 = 31.4159
d. using the whole number of π makes the calculation easier but using the π with more decimals will make the result more accurate.
Answer: hope this helps ♡
a. C = 3 × 10 = 30cm
b. C = 3.14 × 10 = 31.42cm
c. C = 3.14 × 10 = 31.42cm
d. The bigger the estimated value of π, the bigger the circumference. The circumference gets more accurate when you use the whole number of π.
Step-by-step explanation:
C = π ×d (or 2r) d =10
a. π = 3 C = 3 × 10 = 30cm
b. π = 3.14 C = 3.14 × 10 = 31.42cm
c. π = 3.14159 C = 3.14 × 10 = 31.42cm
d. The bigger the estimated value of π, the bigger the circumference. The circumference gets more accurate when you use the whole number of π.

-Graphing Linear equalities with slope and y-intercept-
The slope is equal to -2.
The y-intercept is equal to 1.
The equation is y = -2x + 1.
What is the point-slope form?Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.At point (-1, 3), an equation of this line can be calculated by using the point-slope form:
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 3 = (-1 - 3)/(1 + 1)(x + 1)
y - 3 = -2(x + 1)
y = -2x - 2 + 3
y = -2x + 1

Carissa also has a sink that is shaped like a half-sphere. The sink has a volume of 4500/3 πin3. One day, her sink clogged. She has to use one of two conical cups to scoop the water out of the sink. The sink is completely full when Carissa begins scooping.
(a) One cup has a diameter of 6 in. and a height of 14 in. How many cups of water must Carissa scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number.
(b) One cup has a diameter of 10 in. and a height of 12 in. How many cups of water must she scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number.
By taking the quotient between the volume of the sink and the volume for each cone, we will see that both of your answers are correct.
How many coops does Carissa need to scoop out in each case?
First, we know that the sink has a volume V =
(2000/3)*pi in^3
A) First, she uses a cone of a diameter of 4 in and a height of 8 in.
Remember that the volume of a cone of diameter D and height H is:
V = pi*(D/2)^2*H/3
Then this cone has a volume of:
V = (pi*/3)*(4in/2)^2*8in = (pi/3) 32 in^3
The number of scoops needed to completely remove the water out of the sink is given by the quotient between the two volumes, it is:
Rounding it, we get 63, so she needs to scoop 63 times.
B) This time the diameter is 8 in and the height 8in, so the volume of the cone is:
V" = (pi/3)*(8in/2)^2*8in = (pi/3)*128 in^3
This time, she needs to scoop:
Rounding to the next number we get 16, she needs to scoop 16 times.
So both the answers are correct :)

2/3÷8
2 over 3 divided by 8?
Answer:
To divide 2/3 by 8, we can convert the division into multiplication by taking the reciprocal of the divisor (8) and multiplying it with the dividend (2/3). The reciprocal of 8 is 1/8, so we have:
2/3 ÷ 8 = 2/3 x 1/8
Multiplying the numerators and denominators, we get:
2/3 x 1/8 = 2/24
Simplifying the fraction, we get:
2/24 = 1/12
Therefore, 2/3 ÷ 8 = 1/12.
Step-by-step explanation:
[tex]\frac{2}{3}[/tex] ÷ [tex]\frac{8}{1}[/tex]

What is the area of a rectangle?The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.
Here, dimensions of small rectangle are length=9 ft and width=6.5 ft
Now area of a small rectangle = 9×6.5
= 58.5 square feet
Dimensions of large rectangle are length=18 ft and width=12.2 ft
Here, area of large rectangle = 18×12.2
= 219.6 square feet
Area of the mulch = 219.6-58.5 =161.1 square feet
The mulch cost $4.70 per sq. ft.
Total cost of mulch = 161.1×4.70
= $757.17
Therefore, the total cost of mulch is 757.17 dollars.

If x = 4, what is the y value for the following equation?
y = 12x + 6 - 2x + 2
y = 10
y = 12
y = 48
y = 52
Answer:
y = 48
Step-by-step explanation:
Substitute 4 in place of x in the equationThe equation should be y = 12 (4) + 6 - 2 (4) + 2Following the order of operations, multiple 12 x 4 and -2 x 412 x 4 = 48 and -2 x 4 = 8 Rewrite the equation again to y = 48 + 6 - 8 + 2When we solve the equation, y = 48On a coordinate plane, triangle A has points (3, 3), (6, 3), (6, 9). Triangle A prime has points (negative 2, negative 1), (negative 2, negative 2), (negative 3, negative 2).
Answer: Your welcome!
Step-by-step explanation:
Triangle A prime is a reflection of triangle A across the x-axis. A reflection across the x-axis will switch the sign of the y-coordinates, leaving the x-coordinates unchanged. This means that the x-coordinates of triangle A prime are the same as those of triangle A, but the y-coordinates are opposite in sign. For example, the y-coordinate of the first point of triangle A is 3, so the y-coordinate of the first point of triangle A prime is -1.
