A triangle is placed in a semicircle with a radius of 9 cmFind 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.

Answers

Answer 1

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

Answer 2

Answer:

Final answer:

The area of the shaded region can be found by subtracting the area of the triangle from the area of the semicircle.

Explanation:

To find the area of the shaded region, we need to calculate the area of the semicircle and subtract the area of the triangle from it. First, let's find the area of the semicircle. The formula to find the area of a semicircle is A = (π * $r^2$ ) / 2, where π is approximately 3.14 and r is the radius. Plugging in the values, we have A = (3.14 * $9^2$ ) / 2 = 127.26 square cm.

Next, let's find the area of the triangle. The formula to find the area of a triangle is A = (base * height) / 2. In this case, the base of the triangle is the diameter of the semicircle, which is 2 * 9 = 18 cm. The height of the triangle is the radius of the semicircle, which is 9 cm. Plugging in the values, we have A = (18 * 9) / 2 = 81 square cm.

Finally, to find the area of the shaded region, we subtract the area of the triangle from the area of the semicircle: 127.26 - 81 = 46.26 square cm. So, the area of the shaded region is 46.26 square cm.

The correct answer for the question that is being presented above is this one: Yes, you did answer the problem correctly.

The P(A or B) = P(A) + P(B)
P(A OR B) = 12/15
P(A) = 8/15
P(B) = P(A or B) - P(A)
P(B) = 12/15 - 8/15
P(B) = 4/15
