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

Answer:
Area of the whole rectangle = 11 x 12
= 132 cm^2
Area of the circle = πr^2
= 3.14 x 2 x 2
= 12.56 cm^2
Area of the shaded region = area of rectangle - area of circle
= 132 - 12.56
= 119.44 cm^2
Hope this helps!
Answer:
y = 5
Step-by-step explanation:
Expand the logarithm:

_____
You can also take the antilog first:
5y = y²
y(y -5) = 0 . . . . . subtract 5y, factor
y = 0 or 5 . . . . . y=0 is not a viable solution, so y=5.
