21.3 in^2
hope this helped
Step-by-step explanation:
its .86 which is closer to .87
so choose the first one
Its about finding the equation of a circle from its general form equation:
x^2 + y^2 + 8x - 4y - 61 = 0
x^2 + 8x + 16 + y^2 - 4y + 4 = 61 + 16 + 4
(x + 4)^2 + (y - 2)^2 = 81
therefore the center is C(-4, 2), and the radius is 9
The answer is A. The line indicates that the side are the same. Therefore it’s A.
Answer: 64 - 6 = x
