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 you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
