A:
22π + 2*60
B:
if by "end section" you mean a semi-circle, π*11^2
If the triangle is included, then π*11^2 + 60*22/2
C:
the diagonal of the rectangle has length √(60^2+22^2) = 2√1021
That should enable you to figure the triangle perimeters.
D:
(121π+1320)(1/4)/27
Use the following diagram of a flowerbed of petunias to answer the following questions. This diagram is a rectangle with ½ a circle on each end. The circle diameter is 22 feet, while the length of the rectangle is 60 feet. If you draw an X in the middle of the rectangle, you have 4 different flowerbeds. In the top triangle you will put Petunias, in the bottom triangle you will put rock and shrubs, and in the two side triangles, you will have roses.

A. Find the perimeter of the entire display.
B. The two end sections are filled with assorted wildflowers. Find the combined area of these two sections.
C. Find the perimeter of the section that has rocks and shrubs in it if the top point of bed is exactly in the middle of the flowerbed.
D. Assume you get frustrated with growing flowers, so you decide to CEMENT the ENTIRE flowerbed!! How many cubic yards of cement should you order if you are going to cement this flowerbed 3 inches thick.
