What is the volume formula of a cone?

• SA = B + πrl

• LA = πrl

• V = 1/3 B h

• V = BH

What is the B (area of the base) formula for this cone?

hint...it is a circle base

• B = πr²

• B = 2πr

• B = bh

• B = 1/2bh

Find the volume of the cone.

Round your answers to the nearest tenth.

Use 3.14 for π.

What is the formula for volume of a cube and what is the volume?

• V = Bh

  V = (bh)h

  V = (3)(3)(3)

  V = 27 cm³

• V = Bh

  V = (3)(3)

  V = 9 cm³

• V = Bh

  V = (1/2bh)h

  V = 1/2(3)(3)(3)

  V = 13.5 cm³

What is the formula for density?

• D = m/V

• D = V/m

• D = Bh
