WebNow let's fit a cylinder around a sphere . We must now make the cylinder's height 2r so the sphere fits perfectly inside. The volume of the cylinder is: π × r2 × h = 2 π × r3. The volume of the sphere is: 4 3 π × r3. So the … WebThe surface area of a sphere of radius #r# is #4pi r^2# Imagine dissecting a sphere into a large number of slender pyramids, with apices at the centre and (slightly rounded) bases tesselating the surface. As you use more pyramids, the bases get flatter. The volume of each pyramid is #1/3 xx "base" xx "height"# So the total volume of all the ...
