What is the volume of a cone with a height of 9.5 inches and a radius of 8 inches? Cone V = 1 3 Bh 1. Rewrite the formula for the base area: V = 1 3 πr2h 2. Substitute the values into the formula: V = 1 3 π(82)(9.5) 3.Evaluate the power: V = 1 3 π(64)(9.5) 4.Simplify using multiplication: V = 1 3 π(608) The cone has a volume of Pi inches cubed.
