Answer:
A = 1/2(2πr)(r)
Explanation:
The circumference of the circle, 2πr, is the measure completely around the circle. When the pieces of the circle are rearranged, half of this circumference will be on the top of the parallelogram and half will be on the bottom. This means the base will be 1/2(2πr).
The approximate height of the parallelogram is the radius of the circle; this makes the area
A = 1/2(2πr)(r)
Answer:
Step-by-step explanation:
the triangles are similar because they are proportional. the 3 sides of 2 triangles fall in a particular table.
The answer is actually 164.1 because I learned how to multiply this. :)
