If the equation of a circle is (x + 5)2 + (y - 7)2 = 36, its center point is (5, 7) (-5, 7) (5, -7)
if the equation of a circle is (x + 5)2 + (y - 7)2 = 36, its radius is 6 16 36
if the equation of a circle is (x - 2)2 + (y - 6)2 = 4, the center is point (2, 6).
a. true
b. false
the distance between a (-5, 3) and b(5, 3) is. 3 6 10

Part 1. Center point is ( -5 , 7 ).

Part 2. Radius is 6

Part 3. False

Parts 4. Distance between A & B is 10.

Step-by-step explanation:

Standard Equation of circle is ,

( x - h )² + ( y - k )² = r²

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

Part 1.

Comparing with standard equation of circle we get,

Coordinate of center of circle = ( -5 , 7 )

Thus, 2nd Option is correct.

Part 2.

Comparing with standard equation of circle we get,

radius of circle = 6

Thus, 1st Option is correct.

Part 3.

Comparing with standard equation of circle we get,

Coordinate of center of circle = ( 2 , 3 )

Thus, False.

Part 1.

Distance between two point given by

Distance between A( -5 , 3 ) & B ( 5 , 3 ) =

                                                                  =

                                                                  =

Thus, 3rd Option is correct.
