Fill in the Blanks

The volume of a cone is 803.84 cubic centimeters. If the radius is 8, what is the height of the cone? Use 3.14 for pi

Fill in the Blanks

The volume of a cone is 230.79 cubic centimeters. If the height is 4.5, what is the radius of the cone? Use 3.14 for pi

In Terms of 𝜋

• Do not use 3.14 in your equation

• Just keep 𝜋 symbol

• multiply  $r^2$ (h)...then divide by 3 

Open Ended

Find the volume of the cone in terms of 𝜋.

Open Ended

Find the volume of the cone in terms of 𝜋.

Find height or radius- when given volume. In terms of 𝜋

• Write math sentence

• cancel 𝜋 on both sides

• Multiply the volume by 3 to undo the 1/3.

• Solve- by either squaring the radius and dividing to find height

• or by dividing by height and square rooting your answer to find the radius
