1. Understand the Formula for Surface Area of a Sphere: The surface area A of a sphere is given by the formula: A=4πr2 where r is the radius of the sphere. 2. Set Up the Equation: Given that the surface area A
Given radius of sphere=14cm surface area of sphere=4pir^2 =4xx3.14xx(14)^2 surface area of sphere = 2461.76cm^2
To calculate the surface area of a sphere we multiply 4 by pi by the radius of the sphere squared. Given this formula, we can find the surface area of a sphere when given the radius. Similarly, we can find the radius of a sphere is we are given the surface area. This formula is ...
