Question

What is the radius of a tank that holds 785 cubic feet of oil and is 10 feet tall

Answer 1

The answer to your question is r = 5 ft

Explanation:

Data

Volume = V = 785 ft³

height = h = 10 ft

radius = r = ?

pi = 3.14

Formula

Volume of a cylinder = πr²h

-Substitution

785 = (3.14)r²(10)

-Solve for r²

r² = 785 / (3.14)(10)

-Simplification

r² = 785 / 31.4

r² = 25

-Result

r = 5 ft
