Question

Find



c.S.A of a cylinder whose circumference is 44cm and height 10cm

Answer 1

2 π r is the circumference.

therefore 2πrequals to 44
now Arc aims to be 7 therefore using the formula of the TSA of cylinder that is 2πrh= 2×22/7×7×10=440cm square

Answer 2

$\bold{Solution}$

Given,

● Circumference of cylinder (base) =

44cm

● height of the cylinder =10cm

● Radius =?

To find Curved surface area of cylinder :

$\boxed{c.s.a\:of\:cylinder=2πrh}$

let's begin!!

2πr=44 (Given)

or, 2*22 / 7*r=44

or, r = 44*7/2*22

or, r = 7

$\boxed{Radius=7cm}$

C. S. A = 2πrh

substitute ,

• π = 22/7

• r = 7 cm

• h = 10cm

2*22/7*7*10

or, 440cm^2

$\boxed{C.S.A=440cm^2}$
