Question

Find the surface area of the cylinder in terms of .
4 cm
11 cm

Answer 1

376.991cm^3

Explanation:

surface area of a cylinder formula:

2*pi*r*h+2*pi*r^2

since r=radius(4)

and h=height(11):

2*pi*4*11=276.460154

now,

276.460154+2*pi*4^2

276.460154+100.530965=376.991119

hence, surface area is 376.991cm^3
