Math 10 Week #6

This week we learnt how to to get the surface area of a sphere. The equation to find the surface area of a sphere is 4\cdot pi\cdot r^2.

To find the surface area of a sphere that has a radius of 4.5 feet this is what you do:

4\cdot pi\cdot 4.5^2 = 4\cdot pi\cdot 20.25 = 254.47 ft^2
