Answers
Answer:
Area: 28.26ft², Circumference: 18.84ft
Step-by-step explanation:
Area of a circle: πr²
Circumference of a circle: πd (or 2πr)
Since the diameter is 6ft, then the radius is half of that, which is 3ft. This means that our area is:
πr²
π(3)²
π(9)
9π
9(3.14)
28.26ft²
Our circumference is:

did i do this right “what % of 369 is 26” i got 7.04 so is that the rounded answer (hundredths place) or just 7.0=7?
Answers
Answer:
26 is 7.05% or 7.04% of 369.
Step-by-step explanation:
Now 7.04% of 369 is actually 25.9776.
and 7.04% is 26.01452.
But if you round both 25.9776 and 26.01452 you get 26
So, technically you are correct.

my day was okay. Had school, played some games, did hw, normal stuff. :D
Anywho im going to do my tutor hw and maybe help some other people. Bye!
Answer:
14 cm^2
Step-by-step explanation:
First of all we have to find the total area
total area = lenght x width = 8 x 2 = 16 cm^2
the shaded area is a right triangle
the area of a right triangle is
A = (leg 1 x leg2)/2 = (2 x 2)/2 = 2 cm^2
now we have to subtract it from the total area
16-2 = 14 cm^2

The diagram shows the dimensions of a solid concrete patio in the shape of a right rectangular prism.
How much concrete was used to make the patio?
O A 1.44 m3
OB. 7.80 m
O c. 14.50 m
OD. 30.34 m
Answers
Answer: A
Step-by-step explanation: i multiplied all the sides
The quantity of concrete used to make the patio is 1.44 m³
Since the solid concrete patio is a right rectangular prism, to find the amount of concrete used in making the patio, we find its volume.
So, the volume of the patio, V = lbh where l = length of patio = 4.5 m, b = width of patio = 3.2 m and h = thickness of patio = 0.1 m
So, V = 4.5 m × 3.2 m × 0.1 m = 1.44 m³
The quantity of concrete used to make the patio equals the volume of the patio.
So, the quantity of concrete used to make the patio is 1.44 m³
