Question

A cylindrical propane tank is filled for a cost of $0.03 per in3. The tank has a radius of 24 in. and a height of 60.5 in.

What is the cost to fill the propane tank, rounded to the nearest cent?
Use 3.14 to approximate pi.

Answer 1

Volume of a Cylinder = (pi)*(radius)*(radius)*(height)

pi = 3.14
radius = 24
height = 60.5

so Volume of this Cylinder = (3.14)*(24)*(24)*(60.5)
= 109422.72 in^3

0.03 dollars per in^3 * 109422.72 = 3282.6816

therefore Cost to fill the propane take = $3282.68
