pls mark brainliest!
Answer is choice B: the circumference of a circle is the same as perimeter and is defined by πd (or pi times diameter) We can cut this in half because we are working with a semicircle: so we have 6π which approximates to the value in answer
when using 3.14 for pi
Woops: forgot to add the diameter of 12 so we would have 30.84
So.. 2.86 - 2.79 is the amount in decrease or 0.07
so.. if we take 2.86 as the 100%, how much is 0.07 of that in percentage?
well

solve for "x"
