All triangles have 180 degrees.
Step-by-step explanation:
To find the circumference of a circle you have to multiple the radius by 2 and also by pi. So, to find the radius when given just the circumference, who have to do the reverse operation and divide the circumference by 2 and also by pi to get the answer of 22.92993631, which you could of course round.
150x100= 15,000 square meters
150x2= 300
100 + 300 = 400 meters of fencing
