If the equation of a circle is (x+5)2+(x-7)2= 36, its radius is

6

Step-by-step explanation:

The equation for a circle is (x-h)^2 +(y-k)^2 = r^2

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

(x+5)^2+(y-7)^2= 36

Rewriting

(x+5)^2+(y-7)^2=6^2

The center is at (-5,7) and the radius is 6

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

10+4√2 is the answer. i dont have the time to explain.
