The circumference of a circle is 2•3.14(Pi)•R(radius) or 3.14(Pi)•D(diamater).
Since we have our diameter, 60, we need to multiply it by Pi.
60Pi is your answer.
I hope this helps!
D + 15 - 9 / 3 + 5 the answer is : d + 17
For every 33 green triangles, we have 77 yellow triangles.
So using the original ratio 33:77 we can simplify this by dividing both sides by 11 so that we get the ratio 3:7 so for every 3 green triangles we have 7 yellow triangles.
