Question

The radius of the base of a cylinder is 5cm and its height is 7cm .find its curved surface area. ​

Answer 1

Answer:

CSA = 135.14 CM^2

Step-by-step explanation:

L= ROOT OF H^2+R^2

  = ROOT OF 7^2+ 5^2

   = ROOT OF 49+25

   = ROOT OF 74

L= 8.6 CM

CSA= $\pi$ R L

       = 22/7*5*8.6

       = 135.14 CM^2

Answer 2

Answer:

Base=5cm

Height=7cm

Lateral surface area= 2πrh=220cmAns
