Sergio works at a bakery and needs to cover
eight cylindrical cakes with frosting. The cakes all have the dimensions shown. The bottom of each cake does not need frosting. Find the surface area
he needs to frost on each cake. Use 3.14 for π.

The surface area that Sergio needs to frost on each cake is 3,238 square centimeters

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The surface area of the cylindrical cake is equal to the lateral area plus the area of the top of cylinder (remember that the bottom of the cake does not need frosting)

so

we have

---> the radius is half the diameter

substitute the given values

Round up to the  nearest whole number

therefore

The surface area that Sergio needs to frost on each cake is 3,238 square centimeters

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
