Sylvia has just discovered that the valve on her cement truck failed during the night and that all the contents ran out to form a giant cone of hardened cement. To make an insurance claim, she needs to figure out how much cement is in the cone. The circumference of its base is 44 feet, and it is 5 feet high. Calculate the volume to the nearest cubic foot.

Question

anonymous · Answer

Volume of a cone is 1/3Bh or one third of the base times the height. So use the circumference formula backwards to find the radius. Then you need to use the newfound radius to find the area of the base and then add it into the formula. The area of the base is about 153.9 so the answer is about 256.5
