Atriangle is placed in a semicircle with a radius of 9 cm
find the area of the shaded region. use the value 3.14 for π
, and do not round your answer. be sure to include the correct unit in your answer.

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

32 and 8 respectively

Step-by-step explanation:

Let x be the amount of Kenya city coffee will be added to the blend and y be the amount of Queen city coffee

ATQ, 373.6=8.3x+13.5(40-x), solving it will result in x=32.

So 32 pound of Kenya city and 8 pound of Queen city coffee. Love from Gauthmath
