Elementary Algebra Larson, et al. Math homework help for volume? I got all of the other ones, just can't figure these two out! A manufacturer drills a hole through the center of a metal sphere of radius. The base of a solid is a circular region in the xy-plane bounded by the graph of.

Best answer gets ten points!!! Find the volume of the solid if every cross section by a plane normal to the x-axis, with one side on the Are you sure you want to delete this answer?

There are no dimensions. I just did a problem like this for someone else. See below for a link to the question.

Online Math Homework Help Math homework can be especially tricky because there are so many different formulas and procedures to remember. Students from elementary, through high school, even college, who are experiencing difficulties with their math homework can find some aid online thanks to Internet homework helper sites.

Substitute this formula into the volume formula, and you get V = (pi) r^2 (h). For a cylinder that's three inches tall and has a base with a radius of five inches, here's how you calculate volume: V = (pi) r^2 (h) V = () (5^2) (3) V = () (25) (3) V = cubic inches Spheres. The formula for the volume of a sphere is V = 4/3 (pi) r^3.

For example, the volume of a rectangular prism is measured as its length times width times height. In math language, V=lwh. The volume of a cylinder is π times the radius squared times the height of the cylinder, or V=πr 2 h. The volume of a cone is 1/3 πr 2 h, very similar to the formula of the volume of a cylinder. The volume of a pyramid is 1/3 lwh, which is similar to the formula for the volume of a . Math homework help.
