Answer:
Step-by-step explanation:
Notice that KL = LM and PQ = QR since OL and OQ are perpendicular to both KM and PR.
It follows that QR = (1/2) PR = 20 cm. We also know that MR = 21.
Now in order to solve the problem we just need OQ=OL
Therefore the perimeter of the pentagon is

Question
What is the height of the shape formed by the sectors shown below? A circle is cut into 8 equal sections. The sections are arranged into the shape of a parallelogram with a base of pi r and height of question mark.
a. r
b. d
c. pi times r
d Pi times d
Answer:
a. r
Step-by-step explanation:
In the diagram shown, we can see the sections are divided into 8 and each has a radius of r
The 8 sections from the circle is used to form the a parallelogram.
If we take a look at the diagram of the parallelogram closely, we can see definitely that it still showing the divided 8 equal sections using to form it.
Hence, the height of the parallelogram = the radius of the circle.
Therefore, height of the shape formed by the sectors is r
