Answer:
44
Step-by-step explanation:
The formula to find to area of a circle is = Area
The perimiter formula is = Perimeter
Since we know the area (154cm) we can find the radius (r) with the formula.
You first have to find what the radius of the circle is with.
= 154
3.14=154
Now simplify.
=49 (rounded)
r=7
Now we can find the perimeter with the formula above.
= P
Now plug in.
2(3.14)(7)= P
44=P (Rounded)
