Asked by Saru

A 220g can of baked beans has a height, h, of 7.5 cm and a radius, r, of 3.0 cm. Its surface area is 63π cm2. Its volume is 67.5π cm3 What is the exact surface area of the can?

If you've been given the surface area as 63π cm2 - then the exact amount would be 63 multiplied by pi (3.14159), so exact surface area would be 63 x 3.14159 = 197 cm2
