The volume of sphere with radius 9cm is 3053.63 cm³.
Given:
Radius (r) of the sphere = 9cm
To Find:
The volume (V) of the sphere
Solution:
A sphere is 3 dimensional geometrical analogue to a 2 dimensional shape called circle. It's surface area and volume is based on the radius of the circle; a cross-section of the sphere.
The volume of the sphere can be mathematically represented as:
⇒
- To calculate the volume of sphere mentioned in the question, we know;
r = 9 cm
- Put the value of r in above formula to find the volume:
⇒
⇒
⇒
⇒
⇒ ≈
Hence, the volume of the sphere is 3053.63 cm³
