Perimeter of sphere
WebAug 4, 2024 · It makes sense that 4 π r 2 is the surface area since the then 4 π r 2 d r is the volume of a spherical shell, which represents the added volume. So it's certainly true that 8 π r d r is the incremental change in surface area when we increase the radius of the sphere by d r. WebAnd when a great circle bisects the sphere into two equal parts, they are the hemispheres. Let us see the important formulas. Surface Area of a Sphere = 4 times that of its great circle = 4πr² = πd² Volume of a Sphere = πr² = d³ Solved Example on Cone and Sphere
