Volume of a Sphere - YourTeacher.com - Math Help

For a complete lesson on volume of a sphere, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that the formula for the volume of a cylinder is pi times radius squared times height, so the volume of a cylinder that has a radius of 10 feet and a height of 40 feet is pi times 10 squared times 40, or pi times 100 times 40, or 4000 pi cubic feet. And since pi = 3.14, 4000 pi cubic feet can also be written as 4000 times 3.14, or 12,560 cubic feet. Students also learn that the formula for the volume of a sphere is 4/3 times pi times radius cubed, and the formula for the volume of a cone is 1/3 times pi times radius squared times height.

Bish, it's SSS-F-EAR!! Annoying. Where did she learn English?!?! Can "yourteachermathhelp" find a replacement for her? Her pronunciation sucks, her staccato way of talking sucks, her monotone sucks, and her attitude sucks.... she sucks.
