Answer:
1. V = 94 meters cubed
2. V = 8 feet cubed
3. V = 57 inches cubed
Step-by-step explanation:
The volume of a cone is 1/3 the volume of a cylinder. So all you need to do is plug the numbers into the formula for the volume of a cylinder and then you have the answer.
The formula for a cylinder is V= (3.14 or pi) * radius squared * height
The formula for a cone is V= (3.14 or pi) * radius squared * height * 1/3
So here you go.....
1. V= 3.14 x 9 x 10 x 1/3 V = 94 meters cubed
2. V= 3.14 x 4 x 2 x 1/3 V = 8 feet cubed
3. V = 3.14 x 9 x 6 x 1/3 V = 57 inches cubed
