Question

Drag and drop the symbols to enter the equation of the circle in standard form with center and radius given.

Center (7, 5), radius = 4

Answer 1

Answer: the above answer is right except the last number is 16

Answer 2

The standard equation of a circle with center C(a, b) and radius r is given by:


`(x-a)^2+(y-b)^2=r^2`



thus for C(a, b)=C(7, 5) and radius r=4, the equation is given by:


`(x-a)^2+(y-b)^2=r^2\\\\(x-7)^2+(y-5)^2=4^2`


Answer:


`(x-7)^2+(y-5)^2=4^2`
