Answer:

72 units

Step-by-step explanation:

A circle has a circumference of 452.16

The formula for circumference of circle = $2\pi r$

Where r is the radius of circle

The approximate value of pi = 3.14

Given circumference C= 452.16

$C = 2\pi r$

$452.16 = 2(3.14)r$

$452.16 = (6.28)r$

Divide both sides by 6.28

r = 72

So radius of the circle 72 units

Find me equation of the circle with Center at ( 3, - 2) and radius of 3

blondinia [14]

The equation of a circle with center $(x_0,y_0)$ and radius $r$ is

$(x-x_0)^2+(y-y_0)^2=r^2$

In your case,

$x_0=3,\quad y_0=-2,\quad r=3$

Plug these values into the generic formula and you'll get your equation.
