Question

find the volume of a sphere whose radius is 0.63 metre​

Answer 1

r = 0.63 m or 63 cm

V = 4/3 π r³

= 4/3 × 22/7 × 63 × 63 × 63

= 4 × 22 × 3 × 63 × 63

= 88 × 3 × 63²

= 88 × 11907

= 1047816 cm³ or 1.047 m³

Answer 2

ANSWER:

Given:

The radius of the sphere is 0.63m.

To find:

The volume of the sphere.

Explanation:

We know that the formula of the volume of sphere: $\frac{4}{3} \pi r^{3}$

Therefore,

Volume of sphere= $(\frac{4}{3} *\frac{22}{7} *0.63*0.63*0.63)m^{3}$

Volume of sphere= $(\frac{88}{21} *0.63*0.63*0.63)m^{3}$

Volume of sphere= $(88*0.03*0.63*0.63)m^{3}$

Volume of sphere= 1.047816m³.
