Question

a spherical container with a radius of 4 ft is filled with gas that costs$12 per cubic foot what is the total value of the gas in the container

Answer 1

The spherical container has a radius of 4ft (where ft represents feet)

Its filled with gas that costs $12 per ft³

The value of gas in the container = ?

The volume of a sphere = 4/3$\pi$r³

The volume of the container = 4/3 × $\pi$ × 4³ ft³

One cubic foot = $12

4/3 × $\pi$ × 64 = How much?

Cross multiplying gives:

4/3 × $\pi$ ×64 × $12 = $3216.99 (Rounded up to nearest one cent)
