Question

What is the surface area of a right circular cylinder with base circle of radius of 5m and height of the cylinder 10m?

Answer 1

SA = 2 pi r^2 + 2 pi r h
r = 5, h = 10

SA = 2(3.14)(5^2) + 2(3.14)(5)(10)

I'll leave the math to you.
express answer in sq m

Answer 2

Acylandar has a radius of 8 cm and a height of ro cm. Explain wheather tripiling the height will tripple the volume of the cylindar.
