Question

The curved surface area of a cylinder of radius 7 cm is 154 sq cm​

Answer 1

"

Surface area of base = π*{(7)^2} sq cm

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 154 sq cm.

Surface area of the vertical portion of the cylinder = 2*π*7*50 sq cm

ㅤㅤㅤㅤ = 2200 sq cm.

So, total surface area = (2200 + 154) sq cm

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ = 2354 sq cm.
