Question

Find C.S.A of cylinder whose port circumference
is 44com and height is 10cm ?​

Answer 1

Step-by-step explanation:

H=10 cm

\begin{gathered}2\pi \: r \: = 44 \\ 2 \times \frac{22}{7} \times r = 44 \\ r = \frac{44 \times 7}{2 \times 22} \\ r = 7 \: cm\end{gathered}2πr=442×722×r=44r=2×2244×7r=7cm

CSA=

\begin{gathered}2\pi \: r \: h \: \\ 44 \times 10 \\ 440 \: \: {cm}^{2} \end{gathered}2πrh44×10440cm2

Answer 2

Answer:

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}

c.s.aofcylinder=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}

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}

C.S.A=440cm
