Question

Find the volume of a sphere whose radius is

(i) 7cm
(ii) 0.63m​

Answer 1

Answer:

1)1437.33 cm³

2)1.047816 cm³

Step-by-step explanation:

Given

To find Volume of Sphere of Radius

1) 7 cm

2) 0.63 cm

We Know that,

Volume of Sphere = 4/3 pi r³

1) Volume of Sphere

= 4/3 x 22/7 x 7 x 7 x 7

= 4/3 x 22 x 7 x 7

= 4/3 x 1078

= 1437.33 cm³

2)Volume of Sphere

= 4/3 x 22/7 x 0.63 x 0.63 x 0.63

= 4/3 x 22 x 0.09 x 0.63 x 0.63

= 4/3 x 22 x 0.35721

= 4/3 x 785862

= 1.047816 cm³
