1. The area of the base of a cylinder is 452.16 ft². If the
volume of the cylinder is 2,712.96 ft³, what is the height
of the cylinder?



Answer :

To find the height of the cylinder, we need to use the formula for the volume of a cylinder, which is V = πr²h, where V is the volume, r is the radius of the base, and h is the height of the cylinder. Given: - Area of the base (A) = 452.16 ft² - Volume (V) = 2,712.96 ft³ First, we need to find the radius of the base (r) using the formula for the area of a circle, A = πr². Since the base of a cylinder is a circle, we can find the radius by: 452.16 = πr² r² = 452.16/π r ≈ √(452.16/π) r ≈ √(144) r ≈ 12 ft Now, we can substitute the values of the radius and volume into the volume formula to find the height: 2,712.96 = π(12)²h 2,712.96 = 144πh h = 2,712.96 / 144π h ≈ 6 ft Therefore, the height of the cylinder is approximately 6 feet.
