complete question:

Find the missing dimension of the cylinder. Round your answer to the nearest whole number.

volume = 250 ft³

diameter = 8 ft

h = ___ ft

Answer:

h ≈ 5 ft

Explanation:

The volume of the cylinder is given, likewise the diameter of the cylinder . The volume a cylinder can be represented as

volume = πr²h

where

r = radius

h = height

we were given the diameter, so we find the radius from it diameter .

r = d/2

d = 8 ft

volume = 250 ft³

r = 8/2 = 4 ft

volume = πr²h

250 = π × 4² × h

250 = 16πh

250 = 16 × 22/7 × h

250 = 352h/7

cross multiply

250 × 7 = 352h

1750 = 352 h

divide both sides by 352

h = 1750/352

h = 4.97159090909

h ≈ 5 ft
