Find the circumference and the area of a circle with radius 3 m
Use the value 3.14 for π, and do not round your answers. Be sure to include the correct units in your answers.
Answer:
The area: 28.26m^2, the circumference: 18.85m
Step-by-step explanation:
The area of a circle is 3.14(3)^2, which is 28.26, the circumference is 2(3.14)(3)=18.85m.
Answer:
Area of a circle= π[tex]r^{2}[/tex]
3.14 x [tex]3^{2}[/tex] = 18.84
The area of the circle is 18.84 [tex]m^{2}[/tex]
Circumference of a circle = 2πr
2 x 3.14 x 3 = 18.84
The circumference of the circle is 18.84 m
They are both the same number but the area is squared.
proportional or not proportional?
Answer:
Proportional
Step-by-step explanation:
The relationship is proportional because starting at (0,0) there's a constant rate between the number of plants and the number of roses. We can represent this proportional relationship as y=5x where k=5, the constant of proportionality.

Answer:
First, you would find the area of the trapezoid (I assume), then you would find the area of the circle. Then subtract the area of the circle from the area of trapezoid. Use the following equation:
Area of trapezoid - Area of circle

-10 ≤ 2(2x + 7) ≤ 10.
Answer:
Step-by-step explanation: So first I changed 2(2x + 7) with the distributive property:
4x + 14
Since the above has to be less than or equal to 10, I know that x has to be negative.
If we make x = -1, 4x + 14 simplifies to -4 + 14, which simplifies to 10.
This satisfies the inequality, since it is greater than or equal to -10, and less than or equal to -10.
Hope this explained it well!
Answer:
-6 ≤ x ≤ -1.
Step-by-step explanation:
-10 ≤ 2(2x + 7) ≤ 10
Split it up into 2 inequalities:
2(2x + 7) ≥ -10 (reading from the middle to the left)
4x + 14 ≥ -10
4x ≥ -24
x ≥ -6.
and:
2(2x + 7) ≤ 10
4x + 14 ≤ 10
4x ≤ -4
x ≤ -1.
Combining the 2 we have:
-6 ≤ x ≤ -1.
Evaluate the expression: 25 over 33 divided by x

Answer:
Step-by-step explanation:
7y+5z-2y+z
Group the two y and the two z together
7y-2y = 5y
5z+z= 6z
(a variable with out a number is = to 1)
so it would be 5y+6z

Answer:
D
Step-by-step explanation:
u dont really need a calculator for this problem
to find the answer, you have to look at the equation.
f(x)=20x+4
the 4 is the y-intercept (0,4), which tells us that the range will start from number 4.
the 20x tells u to multiply the x by the 20
so if it was 20(1)=20, 20(2)= 40, 20(3)= 60 ....
so if you add x amount of plates to the barbell, it will be 20 times x plus 4(because 4lbs is the weight of the barbell itself)
so 0 plates is 4, 1 plate is 20(2) + 4 = 44, 20(4)+4= 84 ....
(i didnt do 20(1) or 20(3) because you need to have a even number of plates of each side of the barbell.)
- 4x < 8
