Answer 1

Answer: V = 1649.34

Explanation:

The formula for solving the volume of a right cylinder is V = pi r^2h where r = radius and h = height.

We know that radius is half the diameter so r = 5 because the diameter is 10 ft. We already know height = 21 so our equation looks like pi x 5^2 x 21

5^2 = 5 x 5= 25

so pi x 25 x 21 = 1649.34

Answer 2

V ≈ 1649.34 ft³

Explanation:

Volume of a Cylinder: V = πr²h

Diameter = 2 · radius

Step 1: Define

d = 10 ft

h = 21 ft

Step 2: Substitute and Evaluate

10 = 2r

r = 5

V = π(5)²(21)

V = π(25)(21)

V = 525π

V ≈ 1649.34 ft³
