Da of a sphere
WebThe formula for the volume of a sphere is V = 4/3 π r³, where V = volume and r = radius. The radius of a sphere is half its diameter. So, to calculate the surface area of a sphere given the diameter of the sphere, you can first calculate the radius, then the volume. Created by Sal Khan and Monterey Institute for Technology and Education. Sort by: WebThat is the xy-plane. Now, our sphere, our unit sphere, might look something like this. The unit sphere itself is not too hard to visualize. It might look something like that. The radius-- let me make it very clear. The radius at any point is 1. So this length right over here is 1. That length right over there is 1. And this is a sphere, not ...
