Question

A scientist makes 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 pi

Answer 1

Answer:

The volume of 250 magnets is 625cm³

Step-by-step explanation:

We know that the formula to calculate the volume of a sphere is

v = 3/4 * π * r³

π = 3.14

r = 1.02cm

we replace the values ​​and calculate the volume of a sphere

v = 3/4 * 3.14 * (1.02cm)³

v = 3/4 * 3.14 * 1.061208cm³

v = 2.49914484cm³

to calculate the volume of 250 spheres we simply multiply by 250

250 * 2.49914484cm³ = 624.78621

if we round to the nearest cubic cm

624.78621cm³ = 625cm³
