Area of circle = Pi x r*2
If diameter is 18, radius is 9.
Area = pi (3.14) x r*2 (9*2 = 81) .. 3.14 x 81 = 254.34 sq cen = total area of circle.
A circle is 360 degrees, the shaded area is 270 degrees. the shaded area is 3/4 (270/360) of the area of the circle.
254.34 x 3/4 = 190.755 sq cen
Hope this helps
(-3/5)/7/6
= -3/5 x 6/7
= -18/35

the only solution to the original equation is x = -1.
Answer:
(1) 2x - 6 < - 14
(2) 2x + 3 < 1
Explanation:
(1) 2x - 6 < -14 -> 2x < - 8 -> x < - 4
(2) 2x + 3 < 1 -> 2x < -2 --> x < -1
Compound solution set: x < - 4
