✫ The radius of the sphere is 2 cm✫
Step-by-step explanation:
Given:-
- Height = 4 cm
- Diameter = 4 cm
To find:-
- Radius of sphere
Required Formula:-
- Surface area of sphere = 4πr²
- CSA of right circular cylinder = 2πrh
Solution:-
Where,
- Radius = d/2 = 4/2 = 2 cm
Putting the values,
As here the surface area of a sphere same as the csa of right circular cylinder,so
- ∴ Hence,the radius of the sphere is 2 cm.
