The radius of a circle is the distance from its center to the edge of the circle. The diameter is the length of a line segment t
hat passes through the center and has endpoints on the edge of the circle. How are the radius and the diameter of a circle related? If needed, draw a picture on a piece of paper to help you explain.

Answer:
Step-by-step explanation:
First, we divide the composite figure into two distinct geometric shapes. This would be a triangle and a square. To find the triangle we use the formula:
A = 1/2bh
To find the base of the triangle we can add:
9 + 9 + 18 = 36
Now we plug in and solve:
A = 1/2bh
A = 1/2(36)(27)
= 1/2(972)
= 486
To find the square, we can use length x width:
18×18 = 324
Now, we add the sums together:
486 + 324 = 810
