Question

SOLVE THE FOLLOWING SUBQUESTIONS:
Find the radius of a sphere, if its volume is 904.32cm³ ( π = 3.14).​

Answer 1

Volume of the sphere = 3.14

πr 3

904.32= 3/4

πr 3

100/90432

= 3/4 × 7/2 ×r /3

r × 100 × 4

3 = 90432 ×3

=22/7

r

3

=216 (approx.)

r=6

∴ Radius of the sphere =6cm

Answer 2

Answer:

ok, volume of sphere formula = 4 x π x r ^cube

3

Step-by-step explanation:

therefore, 4 x 3.14 x r ^cube

3

but we know, volume is 904 .32

904.32 = 4/3 x 3.14 x r ^cube

904.32 x 3 = r^ cube

4 x 3.14

2712.96 = r^ cube

12.56

216 = r ^cube

i.e .. 6 x 6 x 6 = 216

therefore x = 6
