Answer:
Step-by-step explanation:
The circumference of a circle = 2*pi * r
so 16 pi yards = 2 * pi * r
Divide both sides by 2
16 pi/2 = 2*pi * r /2
8*pi = pi * r
Divide both sides by pi
8 * pi / pi = pi * r / pi
r = 8
====================
Surface Area = 4 pi * r^2
r = 8
Surface Area = 4 * pi * 64
Surface Area = 256 * pi
Answer:
$754.05
Step-by-step explanation:
We have to find the volume of one tank and multiply it by the cost of renting the tank per cubic foot.
The volume of a cylinder is:

where r = radius
h = height
Each tank has a diameter of 8 feet (radius = 4 feet) and a height of 3 feet.
The volume of the tank is therefore:

The cost of renting is $5 per cubic foot.
Therefore, the cost of renting a tank is:
150.81 * 5 = $754.05
It costs $754.05 to rent a tank.
It will be b because as u see one point I b
