WebSuppose the radius of the sphere is 6 cm, then its volume will be: As we know, the volume of the sphere, V = 4 3 π r 3. Here, r = 6 cm. Thus, volume of sphere, V = 4 3 … WebQuestion 9. The surface area of a sphere of radius 5 cm is five times the area of the curved surface of a cone of radius 4 cm. Find the height of the cone. Solution: Radius of a sphere (r) = 5 cm. ∴ Surface area = 4πr 2. = 4π x 5 x 5 = 100π cm …

Sector of a Circle: Definition, Formula, Area, Perimeter

WebSo if you know the radius, you can calculate the volume. The volume of a cylinder with the same radius and with a height of 2r (since it would be the diameter across) would be V = π r^2 h = 2π r^3. So the empty space of a sphere placed in a cylinder would be V = 2πr^3 - 4/3πr^3 = 2/3 π r3.
