# What is the standard form of the equation of a circle with a center (-5, -7) and a radius of 3.8?

Dec 23, 2015

Standard form: ${\left(x - h\right)}^{2} + {\left(y - k\right)}^{2} = {r}^{2}$

with center $= \left(h , k\right)$ and radius $= r$

#### Explanation:

For this problem, with center $= \left(- 5 , - 7\right)$ and radius $= 3.8$

Standard form: ${\left(x + 5\right)}^{2} + {\left(y + 7\right)}^{2} = {3.8}^{2} = 14.44$

hope that helped
