Given :-
- CSA of cylinder = 88 cm²
- Height of cylinder = 14 cm
To Find :-
- Diameter of base of the cylinder = ?
Solution :-
Let the radius of cylinder be 'r' and Height be 'h'.
According to Question now :-
→ CSA of cylinder = 2πrh
→ 88 = 2 × 22/7 × r × 14
→ 88 = 2 × 22 × r × 2
→ 88 = 88r
→ r = 88 ÷ 88
→ r = 1 cm
Therefore,radius of right circular cylinder is 1 cm.
Now, let's find the diameter of the base of cylinder :
→ Diameter = Radius × 2
→ Diameter = 1 × 2
→ Diameter = 2 cm
Therefore,radius of base of cylinder is 2 cm.
