A baker needs to cover a cylinder cake with icing. The cake has a radius of 5 inches and a height of 7 inches. How many square inches of icing will be needed to cover the sides and top of the cake? Icing will not be added to the bottom of the cake. Use 3.14 for pi and round your answer to the nearest tenth.(1 point)
THE ANSWER IS NOOOOOOT 376.8
The formula needed to find the surface area of the sides and top of the cylinder cake is 2πrh + πr^2.
First, let's find the radius (r) and height (h):
r = 5 inches
h = 7 inches
Substitute these values into the formula:
Surface area = 2(3.14)(5)(7) + (3.14)(5)^2
Surface area = 2(3.14)(35) + (3.14)(25)
Surface area = 219.8 + 78.5
Surface area = 298.3 square inches
Therefore, the baker will need 298.3 square inches of icing to cover the sides and top of the cake.
