Answer 1

QUESTiON

• Find the volume of sphere with radius 6 cm

SOLUTiON

• Volume of Sphere = 4πr³/3
• Volume of Sphere = 4π6³/3
• Volume of Sphere = 4×3.14×72
• Volume of Sphere = 904.32

AÑSWER

• Volume of Sphere = 904 cm³

Answer 2

Answer :

Given the radius of the sphere is 6 cm

volume of sphere=

$\frac{4}{3} \pi {r}^{3}$

where r is the radius of the sphere

$\frac{4}{3} \times \frac{22}{7} \times 6 \times 6 \times 6 = \frac{4 \times 22 \times 72}{7} \\ = \frac{6336}{7} = 905.142 \: {cm}^{2}$

hope it helps you ✌️✅✅✅
