A triangle has sides that measure 4 units, 6 units, and 7.21 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.

24 units * I used this and it was correct*

Step-by-step explanation

1. Add all sides to get the perimeter of the triangle which is also the perimeter / circumference of the circle.

4 + 6 = 10 ... 10 + 7.21 = 17.21

2. Now just solve this as an algebraic expression and plug in ...

C=π (d)

17.21 = π (d) * cancel out pi*

17.21/π = π/π (d)

5.48089172 = d

3. So now that you have the diameter you divide it by 2 to get the radius ... r = 2.74044586

4. So now you have all the variables to solve for the area of the circle ...

A = π (r²)

A = π (2.74044586²)

A = π (7.510043511)

A = 23.58153662

A = 24 * rounded*

Note that π = 3.14
