Question 13 Multiple Choice Worth 4 points) (06.01 MC)
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 forn, and
round your answer to the nearest whole number.
22 units
157 units?
39 units
70 units

Step by step: Perimeter of triangle=7+6+9.22
=22.22unit
Circumference of the circle=22.22units
Circumference= (diameter)
22.22=3.14 x diameter
Diameter=22.22/3.14
Diameter=7.0764 (4 decimal places)
Radius=7.0764/2
=3.5382
Area of circle=3.14 x 3.5382^2
=39.3 units (3 Significant Figures)
Therefore, 39 units is correct.

Lengthy so you could understand better hopefully.
