Question

If the height is 9 units and the volume is 36 cubic units, what is the surface area of a right circular cylinder?

(Hint: Surface Area of a Cylinder = 2 • • r • h + 2 • • r2
Volume of a Cylinder = • r2 • h)











If the height is 9 units and the volume is 36 cubic units, what is the surface area of a right circular cylinder?

(Hint: Surface Area of a Cylinder = 2 • • r • h + 2 • • r2
Volume of a Cylinder = • r2 • h)

Answer 1

Actually, the vol. of a cyl. is \[V _{cyl}=\pi r^2 h\]

Answer 2

You are given the volume and the height. What is the area of the circular base?
