Question

If the diameter of the base of a closed right circular cylinder is equal to its height. Find the total surface area.

Answer 1

Answer:

Diameter=height of cylinder=h

radius = half of diameter=h2

whole surface area= 2πr2+2πrh

=> Answer-32×πh2

Answer 2

Answer:

Step-by-step explanation:

Height = h

Diameter = h

radius = h/2

Surface area = curved surface area + area of base and top

                    = 2πrh + 2πr²

                    = 2πr(r+h)

                    =2×π×h/2( h+h/2)

                    = πh(3h/2)

                    =3πh²/2
