Atriangle has sides that measure 2 units, 5 units, and 5.39 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.
39 units²
25 units²
49 units²
12 units²

12

units^2

step-by-step explanation:

step-by-step explanation:

in order to find the area of the circle, we need its radius (r).

if perimeter of the triangle is equal to the circumference of the circle then we can write:

perimeter=5+2+5.39=12.39 = circumference=2pi(r)

solving for r, we get r=12.39/2pi = 1.97

so the area of the circle = pi(r)^2 = pi(1.97)^2 =12.19

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
