Question

A cylinder is 8 m high and the circumference of its base is 22 m. Find its curved surface
area
​

Answer 1

Answer:

here's your answer

Step-by-step explanation:

H=8m

Circumference=22m =

$pi {r}^{2}$

therefore,

$pi {r}^{2} = 22m$

therefore put the value of pi,

22/7×

${r}^{2} = 22m$

r square =22×7/22

therefore r square= 7

therefore r=

$\sqrt{7}$

then you have to apply the formula of curved surface area os cylinder then you get your answer

Answer 2

Answer:

176 m^2

Step-by-step explanation:

Circumference = 2×pie×r

22 = 2×22/7×r

22×7 = 44r

154 = 44r

154/44 = r

•°• radius is 3.5 m.

Curved Surface Area ( CSA )=2×pie

× r× h

=2×22/7×3.5×8

= 44 × 0.5 × 8

= 44 × 4

= 176 m^2 is the answer.
