Propane is stored in a cylindrical tank with a diameter of 15 inches and a height of 48 inches. Which equation could be used to
Virty [35]

Step-by-step explanation:

remember. the radius is always half the diameter.

volume of a cylinder

pi × r² × height

pi×7.5²×48 = pi×56.25×48 = 8,482.300165... in³

volume of a sphere

4/3 × pi × r³

and that volume should be the same as the cylinder. so,

4/3 × pi × r³ = pi×56.25×48

4/3 × r³ = 56.25 × 48

1/3 × r³ = 56.25 × 12

r³ = 56.25 × 36 = 7.5² × 6² = (7.5×6)² = 45² = 2025

r =  \sqrt[3]{2025}

which would be 12.65148998... in.

You can multiply the fraction by any number you want so the new fraction gonna be equivalent to your fraction like : (4 × 2)/(5 × 2) = 8/10 or  (4 × 3) / ( 5×3) = 12/15 so 4/5 = 8/10 = 12/15 :))
