Find the volume of a sphere whose radius is 0.63 m.
Given,
Radius of the sphere (r) = 0.63 m
By formula,
Volume of the sphere = 43πr3\dfrac{4}{3}πr^334πr3
Substituting values we get :
=43×227×(0.63)3=43×227×0.250047=8821×0.250047=22.00421=1.05 m3= \dfrac{4}{3} \times \dfrac{22}{7} \times (0.63)^3 \\[1em] = \dfrac{4}{3} \times \dfrac{22}{7} \times 0.250047 \\[1em] = \dfrac{88}{21} \times 0.250047 \\[1em] = \dfrac{22.004}{21} \\[1em] = \text{1.05 m}^3=34×722×(0.63)3=34×722×0.250047=2188×0.250047=2122.004=1.05 m3
Hence, the volume of sphere = 1.05 m3.
