Oriya is making a four layered wedding cake her cake is I the shape of a cylinder with a radius of 6inches each layer has a height of 2inches what is the total surface area of priyas four cake layers before stacking use 3.14 for and round to the nearest hundredths

Answer 1

To find the total surface area of Priya's four cake layers, we need to find the surface area of one layer and then multiply that by 4 since there are four layers.

The formula for the surface area of a cylinder is:
Surface Area = 2πr(r + h)

Given that the radius, r, is 6 inches and the height, h, is 2 inches, we can plug these values into the formula to find the surface area of one layer:
Surface Area = 2 * 3.14 * 6(6 + 2)
Surface Area = 2 * 3.14 * 6(8)
Surface Area = 2 * 3.14 * 48
Surface Area = 301.44 square inches

Now, we multiply this by 4 to find the total surface area of all four layers:
Total Surface Area = 301.44 * 4
Total Surface Area = 1205.76 square inches

Therefore, the total surface area of Priya's four cake layers before stacking is 1205.76 square inches.
