Question

1. Find the volume of a sphere whose radius is
1) 7 cm
(ii) 0.63 m​

Answer 1

Answer:

volume of sphere = 4/3 pie r^3

4/3 *22/7 * 7 ^3

4/3*22/7*343

30184/21

= 1437.33. Ans

Answer 2

Step-by-step explanation:

13.8 1 Find the volume of a sphere whose radius is 7 cm Radius = 7 cm Volume of sphere = 4/3 r3 = (4/3 22/7 7 7 7) cm3 = (4/3 22 1 7 7) cm3 = 4312/3 cm3 = 1437.33 cm3 Ex 13.8 1 Find the volume of a sphere whose radius is (ii) 0.63 m Radius = 0.63 m Volume of sphere = 4/3 r3 = 4/3 22/7 0.63 0.63 0.63 m3 = 4/3 22/7 63 ...
