Answer:
B
Step-by-step explanation:
find the area of the rectangle and then find the area of the semi circle, then add the 2 together
We know the area of the middle rectangle is 48 (length * width). removing that rectangle leaves us with two semicircles. you can combine those semicircles to be the equivalent of one circle. the area for a circle is r^2 * pi. we know the diameter is 4 because that is where we cut the semicircles. radius is half the diameter, so r is 2. 2^2 is 4, 4* pi is 12.56. add 12.56 (area of semicircles) with 48 (area of rectangle) and we get 60.56
Answer:
15
Step-by-step explanation:
a right angle is 90 degrees, so if you divide that by 6 you get one sixth of the angle
