What is the volume of a sphere with a diameter of 10 cm? Use 3.14 for pi and round to the nearest tenths.

The volume of the sphere is 523.3in³

Step-by-step explanation:

radius = half of diameter

d = 10cm

r = 10cm / 2 = 5cm

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius = 5cm

π = 3.14

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * 3.14 * (5cm) ³

V = 4.187 * 125cm³

V = 523.333in³

Round to the nearest tenth

V = 523.333in³ = 523.3in³

The volume of the sphere is 523.3in³

The volume of the spear is 523.3in 3
