Answer:
Step-by-step explanation:
1 = (20 x 70) + (70 x 20) = 1400 x 2 = 2800 squared meters
2 = 9.18 x 2 = 18.36 + 9.72 = 28.08 squared centimeters
3 = 9 x 4 = 36 + 6 + 3 = 45 squared units
Y= -2(x²-x)+2= -2(x-1/2)²+2+1/2= -2(x-1/2)²+5/2
<span>x=6, y= -2(11/2)²+5/2= -121/2+5/2= -58
I hope this helps</span>
The circumference of the circle is equal to the perimeter of the triangle, then the area of the circle is 12 square units. Option D is correct.
<h3>What is a circle?</h3>
It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
A triangle has sides that measure 2 units, 5 units, and 5.39 units.
The circumference of the circle is equal to the perimeter of the triangle. Then the radius of the circle will be

Then the area of the circle will be

The area of the circle is 12 square units.
