Answer:
150.72 cm^2
Step-by-step explanation:
The blue area has an angle of 120 degrees, and 120/360 = 1/3, which shows that the blue area is 1/3 of the circle. In that case, the blue area is just 144pi/3. That simplifies to 48 pi.
48*3.14 = 150.72
All of the angles in a triangle should add up to 180 degrees so if you know 2 out of three you just do subtract 180 by the sum of the two angles.
180-85=95
Answer:
7X8
Step-by-step explanation:
There is 7 spaces along one side and 8 along the other, area=l x w (length multiplied by width)
5x13=65 (area of the rectangle)
5x6x½=15 (area of the triangle)
so 65+15=80
