The easiest, simplest way to determine if a quadrilateral has a congruent angle is to pull out a protractor and measure the angles. How ever many angles have the same degrees is how many congruent angles a quadrilateral has.<span />
First, find the radius

r=circumference
r=18

r=9 cm
Now, we can just use the circle area formula to solve

Answer:
7
Step-by-step explanation:
4 ÷ 2 = 2
2 × 5 = 10
17 - 10 = 7
Answer:
The answer should be A......
Area = W * L55 = 5 * L55/5 = L11 = L
Note "L" is the length.
