Question

The volume of a cylinder, given by the formula V = πr2h, is 539 cubic inches. In the formula, r represents the radius and h represents the height of the cylinder. Which equation represents the value of r in terms of h?

Answer 1

Explanation:

539 = π × r^{2} × h

÷ πh

539 ÷ (π × h) = r^{2}

√

√(539/π × h) = r

Answer 2

r =(7/2) * (√ 7/h)

Explanation:

V = πr²h

(22/7) * r²h = 539 cubic inches

r² = 539 * 7

22 * 2 * h

r² = 49 * 7

2 * 2 *h

r =(7/2) * (√ 7/h)
