Surface Area of sphere = 4πr2 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 r2 = 4π (3.2)2 = 4 × 3.14 × 3.2 × 3.2
Therefore, the volume of the sphere is 2(1/3 *pi* r squared*2r.) Multiplying the constants in this expression results in 4/3. What is the radius of a sphere? The sphere is a three-dimensional figure with a fixed point called the center. The radius of the sphere is the distance ...
