B is the common answer, so I choose B
1 = 135, 2 = 45, 3 = 135, and angle 4 = 45. Please include a picture next time.
First, get the area of the square field. The area of the square is side multiplied by side. A = S x S A = 12 X 12 A = 144 meters squared Second, get the area of the circle formed by the sprinkler. The circle is formed inside the square with a radius of 6
A = pi * r^2 A = 3.14 * 50^2 A = 7,850 square miles (area of the 50 mile broadcast signal) A = pi * r^2 A = 3.14 * 75^2 A = 17,662.5 = 17,663 square miles (area of the 75 mile relayed signal) Now we just need to subtract the 50 mile signal from the 75 mile
Radius is 3 Pi times 3^2 = 28.27 rounded A = 28.27 rounded
You forgot to say that the diameter of the Farris wheel is 62 feet, I know this because I got the same question. Here's the answer C = pi times diameter C = 3.14 times 62 diameter The circumference is 197.82 feet Then you multiply to get your answer 197.82
