a triangle has sides that measure 7 units, 6 units, and 9.22 units. what is the area of a circle with a circumference that equals the perimeter of the triangle? use 3.14 for π, and round your answer to the nearest whole number.

22 units squared

157 units squared

39 units squared

70 units squared

39 units squared

Step-by-step explanation:

circumference of circle =sum of sides of triangle (22.22)

Formula circumference  2*pi*r

     22.22=2*pi*r

r=22.22/2pi                

r=22.22/6.28

r=3.5382 (radius is 3.5382...)

Formula area      pi*r^

r^ = (3.5382)^ =12.5289

(12.5189)(*3.14)= 39.30

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
