A globe has a surface area of 2700 cm². Andrew wants to estimate the volume of the globe. To do the estimate, he approximates π using 3 in both the surface area and volume formulas for a sphere.

Using this method, what value does he get for the approximate volume of the globe?

Volume/Area =[4/3 x 3 x r^3] / [4 x 3 x r^2] =r/3, where r = radius.

Radius =sqrt[2,700/(3x4)] =15 cm

Volume =2,700 x 15/3

Volume =13,500 cm^3
