Question

A scientists makes a spherical magnets. Each magnet has a radius of 1.02 cm. They are stored away in boxes of 250. Calculate the volume of 250 magnets, to the nearest cubic cm. Use 3.14 for pie

​

Answer 1

The volume of a sphere is given by

`V = (4)/(3)\pi r^3`

If we use
`\pi \approx 3.14`, we get

`V = (4)/(3)\cdot 3.14 \cdot 1.02^3 \approx 4.44` cubic centimeters

So, the volume of 250 spheres is

`250\cdot 4.44 \approx 1110.73` cubic centimeters
