Question

QUESTION:Suppose a cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cylinder in cubic feet?

ANSWERS:

A V = π(18h)2V = π ( 18 h ) 2

B V = π(9)2hV = π ( 9 ) 2 h

C V = π(18)2hV = π ( 18 ) 2 h

D V = π(9h)2

Answer 1

B

Explanation:

π(9)2hV = π ( 9 ) 2 h

Answer 2

Answer: B
`v=\pi 9^(2) h`

Explanation:

to find volume use V=π r^2 h

if the diameter is 18 feet then the radius (r) will be half of that, 9 ft. So, to find the volume we'd just replace the r with 9 in the equation.
