Question

Which equation represents a circle with the center at two, -8 and a radius of 11

Answer 1

(x - 2)² + (y + 8)² = 11²

Explanation:

General equation for a circle

( x - h )² + ( y - k )² = r², where (h,k) is the center and r ,radius..

with center ( 2,-8 ) and radius 11

(x - 2)² + (y + 8)² = 11²

Answer 2

( x-2)^2 + ( y +8) ^2 =121

Explanation:

The equation of a circle can be written as

( x-h)^2 + ( y-k) ^2 = r^2

where ( h,k) is the center of the circle and r is the radius

( x-2)^2 + ( y- -8) ^2 = 11^2

( x-2)^2 + ( y +8) ^2 =121
