Super-yummy soup, inc. wants to paint their entire soup can red, including the top and bottom. if the diameter of the lid (x) is 5 cm, and the height of the can (y) is 9 cm, what is the approximate total surface area that will need to be painted?

Respuesta :

top and bottom = 5^2 * pi = 78.54
rest of the can = 9 * (10pi) = 9*31.4159 = 282.74
top and bottom + the rest of the can = 78.54 + 282.74
= 361.28cm^2
