Answer 2

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.
