Circumference of a circle is 2(pi)(r)
2(3.14)(7)= 43.96
So the answer is B
Hello!
I was looking for this answer as well, but I took the quiz and got it correct. The answer is 5 units.
good luck!
24/4: 24-12: 12+0: 12/1: 48/4: 72/6:
Assuming that c is the length of AB (as is usually the case in the angle-side notation for triangles):
If sin(35) = 12/c, we can transform by multiplying both sides by c, and dividing both by sin(35) to get
c = 12/sin(35)
Evaluating using a calculator gives 20.92 units.
