Question

Find the curved surface area of a right circular cylinder circumference of whose base is 88cm and height is 5cm?​

Answer 1

Answer:

Answer: 440 cm² is the right answer

Answer 2

Answer:

Let the radius be r

$Circumference = 2\pi \: r$

88 =2 * 22/7 *r

88 * 7/22 * 2 = r

R = 14 cm

CSA = 2pi rh

2 * 22/7 * 14 * 5

2*22*2*5

440cm²
