WebSurface Area of sphere = 4πr 2. where r is the radius of the sphere. Example: Calculate the surface area of a sphere with radius 3.2 cm. Solution: Surface area of sphere = 4π r 2 = 4π (3.2) 2 = 4 × 3.14 × 3.2 × 3.2 = 128.6 cm 2. … 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 sphere's …
