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
​

Respuesta :

The volume of a sphere is given by

[tex] V = \dfrac{4}{3}\pi r^3 [/tex]

If we use [tex] \pi \approx 3.14 [/tex], we get

[tex] V = \dfrac{4}{3}\cdot 3.14 \cdot 1.02^3 \approx 4.44 [/tex] cubic centimeters

So, the volume of 250 spheres is

[tex] 250\cdot 4.44 \approx 1110.73 [/tex] cubic centimeters
