Surface Area and Volume of Cylinders (9)

Calculate the surface area and volume of cylinders and solve related problems (ACMMG217)

LO:To find surface area and volume of cylinders


Know:

  • the formula for calculating the area of circles
  • the formula for calculating the volume of prisms

Understand:

  • That formulas can be used to quickly find the surface area and volume of cylinders.

Do:

  • I can find the surface area and volume of cylinders.

Surface Area of Cylinders

A cylinder is basically made up of 3 shapes, the top, bottom and the side. The top and bottom should be congruent so we only need to calculate one of the sides then double it.
Area of top/bottom = ∏ x r x r
Area of side = 2 x ∏ x r x h
Formula: 2 x ∏ x r x r + 2 x ∏ x r x h


 

Volume of Cylinders

A cylinder is essentially a circular prism, so all we need to do is find the area of the circle then multiply it by the height.

Formula: ∏ x r x r x h
