Given :-
- Height of right circular cylinder = 14 cm
- Curved surface area = 88 cm²
To find :- Diameter of the base.
Formula for Curved surface are:-
In which C.S.A is curved surface area , r is Radius and h is height.
Now , Substitute the values in above formula.
→ 88 = 2 × 22/7 × r × 14
→ 88 = 88 × r
→ 88 / 88 = r
→ 1 cm = r
So, Radius of right circular cylinder is 1 cm
We know that
In which D is diameter of base and r is Radius.
- Put Radius is formula.
→D = 2 × 1
→ D = 2 cm
Hence diameter of base is 2 cm.
