Question

Find the total surface area of the cylinder if the radius of its base is 5cm and hight is 40cm

Answer 1

Given that

r = 5 cm

h = 40 cm

The formula to find the Surface Area of cylinder is

A = 2 π r h + 2 π r^2 or

A = 2 π r ( h + r )

A = 2 (22/7)(5)(40+5)

A = 1414 cm^2 is the required surface area
