Hi The Answer to this would be approxiametly 154 and that's rounding up. I'm going to explain how I got it. First off we have to find the radius before we can get the area and to do this we use the formula $C=2 \pi (r)$ where r equals the radius of the circle. Now we can plug in our values C Would be replaced with 44 and then the formula would like $44=2 \pi (r)$ . Then we divide both sides of the equation by 2 so it would look like 44/2 = 22 you dont need to bring the 2 down from the other side. Now its $22= \pi (r)$ . Now we divide both sides of the equation by Pi which equals to 3.14. So 22 divided by 3.14 equals 7. Now we have found the radius so R=7. Now we calculate the area. The formula for area is $A= \pi (r^2)$ which means area equals pi times radius squared. 7 squared would be 49. Which the formula would like $area= \pi (r^2)
area= \pi (7^2)
area= \pi (49)
area=(153.86)$ You can round 153.86 to 154.06. We got that from squaring 7 which is 49 and 49 multipled by 3.14 (PI) equals 153.86. Comment if you need me to explain more. Hope this helped :)
