Question

If the equation of a circle is (x + 5)2 + (y - 7)2 = 36, its radius is 6 0 0

Answer 1

Answer:

6

Step-by-step explanation:

Radius of the given circle is 6 units.

Given equation of circle is:

${(x + 5)}^{2} + {(y - 7)}^{2} = 36 \\ \: equating \: it \: with \\ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ {r}^{2} = 36 \\ \huge \red{ \boxed{r = 6 \: units}}$
