Lesson Objective
We will be able to calculate the volume of a cylinder.
Lesson Plan
Do Now: (5 minutes)
1) Find the volume of this prism. (4ft x 8ft x 6 ft)
1) Find the volume of this prism. (4ft x 8ft x 6 ft)
2) Find the area of this circle. radius = 4 inches
Direct Instruction: (20 minutes)
Yesterday we found the volume of prisms. For a rectangular prism, all we had to do was multiply length times width times height. However, it got a little more complicated with triangular prisms. What did we have to do to find the area of a triangular prism?
Today we are going to find the volume of a cylinder. Since we know that volume tells us how much a solid holds, what do you think we would have to do to find the volume of a cylinder?
How would we calculate B?
V = Bh, where B= area of base or V = πr²h
Ex. Find the volume of a cylinder with a radius of 5 cm and a height of 8.3 cm. (draw cylinder)
