Isabella uses the equation V = one-third (12) squared (9) pi to find the volume of the cone below.
A cone has a height of 9 centimeters and base of 12 pi centimeters squared.
What is Isabella’s error?
Isabella should have divided 12 by 2 before squaring to get V = one-third (6) squared (9) pi.
Isabella should have squared 9 instead of 12 to get V = one-third (9) squared (12) pi.
Isabella should have divided the product of 12 and 9 by 3 to get V = StartFraction 12 (9) Over 3 EndFraction.
Isabella should have divided the product of 12 pi and 9 by 3 to get V = StartFraction 12 pi (9) Over 3 EndFraction.
Isabella should have divided the product of 12 and 9 by 3 to get V = StartFraction 12 (9) Over 3 EndFraction.

3 cm
4 cm
6 cm
8 cm
The measure of the radius of the cone is 4 cm.
A cone has a height of 2.5 in. and a radius of 5 in. What is the volume of the cone? (Use 3.14 for Pi. Round the answer to two decimal places.)
32.71 Inches cubed
65.42 Inches cubed
196.25 Inches cubed
588.75 Inches cubed
The volume of the cone can be calculated using the formula V = (1/3)πr²h, where r is the radius and h is the height.
Plugging in the values, V = (1/3) * 3.14 * 5² * 2.5 = 65.42 inches cubed.
Therefore, the volume of the cone is approximately 65.42 Inches cubed.
What number can be used to complete the volume statement for the cone?
A cone with height 4 meters and diameter 3 meters.
Volume =
Pi meters cubed
