Find the center of the circle whose equation is (x - 8) 2 + (y + 2) 2 = 64. (8, 2) (-8, 2) (8, -2)

If given the equation, you need to take the number beside the x and y and change their signs to get your point:

x - 8 (Take the -8 and make it +8)

y + 2 (Take the +2 and make it -2)

Your point is (8, -2)

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

if you was gonna solve for a, a is a   < -12
