Question

The curved surface area of a right circular cylinder of height 14 cm is 88 cm. Find the
diameter of the base of the cylinder.​

Answer 1

Answer:

Height (h) of cylinder = 14 cm

Let the diameter of the cylinder be d.

Curved surface area of cylinder = 88 cm2

⇒ 2πrh = 88 cm2 (r is the radius of the base of the cylinder)

⇒ πdh = 88 cm2 (d = 2r)

⇒ 22/7 x d x 14cm = 88 cm2

⇒ d = 2cm

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

Hope this will help!!

Answer 2

Answer:

2cm

Step-by-step explanation:

c.s.a of cylinder=88cm²

height=14cm

diameter=?

so we know that curved surface area of cylinder is 2×π×r×h

therefore,

c.s.a of cylinder=2πrh

88. =2×22/7×r×h

88. = 2×22/7×r×14

88. =2×44r

88. =88r

88/88 =r

1cm = r

we know r is double of diameter

so diameter=1×2=2cm
