PLEASE ANSWER!!!!!!
The semicircle below has a diameter of 20. Find the area of the blue region.

Answers

Answer:

61

Step-by-step explanation:

Use the area of semicircle minus the area of the triangle. Area of the semicircle is 10^2 * pi / 2 = 50 pi, the area of the triangle is 12*16/ 2 = 96. The the area for the blue part is 50 pi - 96 = 61.07963268 or 61.

If it is helpful, plz give me Brainliest.

Answer:

50pi - 96

Step-by-step explanation:

The radius of the semicircle is 10, so the area of the entire semicircle is 1.2*10^2 pi = 50pi

The white triangle has an area of 1/2*12*16 = 96 so subtracting it shows that the blue area is 50pi-96

Arwa is playing 'Guess my number'. Arwa says: 'If I add 0.4 to my number, divide the answer by 8, then multiply that answer by 9, I get 0.9.' What is Arwa's number?

Answers

0.4 is the answer because you if you work backwards and use inverse operations you get 0.4.
meaning, if you divide 0.9 by 9, you get 0.1. when you multiply 0.1 and 8 you get 0.8. and when you subtract 0.4 from 0.8 you get your answer, 0.4.

Answer:

65°

Step-by-step explanation:

the angle of a straight line has to add up to 180°

if it doesn't, it's not a straight line

115° and x are supplementary angles

meaning we know they have to add up to 180°

so simply subtract

180- 115 =

65°

you can check work by adding

115+65= 180

Answer: 65

180-115=65

Step-by-step explanation:

A straight line is always 180 so I subtracted 115 from 180.

What is the area of a triangle?

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

From the given figure,

Height of a triangle is 8 units and the base of the triangle is 6 units.

Here, area = 1/2 ×6×8

= 24 square units

Therefore, option B is the correct answer.

In order to find the area of a polygon, all you have to do is follow the formula: area = 1/2 x perimeter c apothem. To sum it together, perimeter = the sum of the lengths of all the sides. So add 6, 16, 16, 6, 4, 6, 28, and 18! And then you have 100! Then multiply it by 1/2! So your answer should be 50. Please consider brainliest.
