Question

the curved surface area of a right circular cylinder of height 14 cm is 88 CM square find the diameter of the base of the cylinder

Answer 1

CSA of cylinder = 88 cm2

2 pie r h = 88

2× 22/7 × r × 14 = 88

44× 14 r = 88 × 7

r = (88× 7 ) ÷ (44×14)

r = 1 cm

DIAMETER = 2× 1 = 2 cm

Answer 2

Answer:

Step-by-step explanation:

Given :-

Height (h) = 14 cm

Curved surface area = 88 cm2

To Find :-

Diameter of the base of the cylinder.

Formula to be used :-

Curved surface area = 2πrh

Solution :-

2πrh = 88 cm2

⇒ 2 × 22/7 × r × 14 = 88 cm2

⇒ 88r = 88

⇒ r = 88/88

⇒ r = 1 cm

Then diameter = 1 × 2 = 2 cm

Hence,  the diameter of the base of the cylinder is 2 cm.
