use 3.14 as by then find the volume of a sphere whose:

1. r = 8 cm
2. d = 9 m
3. d = 10 ft.
4. r = 12 dm
5. r = 15 cm​

Answer:

1. r = 8 cm = V=4/3πr^3=4/3·π·8^3≈2144.66058

2. d = 9 m = V = 4/3πr^3=4^3·π·4.5^3≈381.70351

3. d = 10 ft. = V=4/3πr^3=4/3·π·5^3≈523.59878

4. r = 12 dm = V=4/3πr^3=4/3·π·12^3≈7238.22947

5. r = 15 cm = V=4/3πr^3=4/3·π·15^3≈14137.16694
