Answer:
From left to right
All real numbers
All positive real numbers and zero
All real numbers except 2<_x<_5
All real numbers except 1<_x<_4
Step-by-step explanation:
Considering that the shaded area is the part of the semi circle outside the triangle:
Area of circle= Pi x radius2 (this means radius squared)
Area of triangle= 1/2 x base x height
1/2 (because it is a semi circle) x 3.14 (in replacement of pi as directed by question) x 9squared= 127.17
127.17 - (1/2 x 18 x 9) = 46.17cmsquared
It’s 101 because 72 and -29 have a difference of 101
