# Find the volume of a sphere whose radius is 0.63 m - Mathematics

Find the volume of a sphere whose radius is 0.63 m

["Assume "pi=22/7]

#### Solution

Radius of sphere = 0.63 m

"Volume of sphere "= 4/3pir^3

=[4/3xx22/7xx(0.63)^3]m^3

= 1.0478 m3

Therefore, the volume of the sphere is 1.05 m3 (approximately).
