<span>The area to be determined is a segment of the circle.
Since central angle is 120 degrees and 120/360 = 1/3
area of sector of circle is (1/3)*36pi = 12pi
For the area of triangle, you can split it into 2 30-60-90 right triangles with sides 3:3sqrt3:6
thus base of triangle is 6sqrt3 and height is 3
Area = 1/2 * 3* 6sqrt3 = 9sqrt3 -->
segment area = 12pi - 9sqrt3</span>
Answer:
A=πr2 is the formula of pi so
it would be A=3.14*100
or 3.14*10^2
3.142 is not pi
and 20 is not 10^2
Step-by-step explanation:
192 - 5x < 50
192 < 50 + 5x
142 < 5x
28.4 < x
