Question

Easy question about a circle :)

Answer 1

Answer:

Radius of Circle

radius  =$\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }$

radius  = $\sqrt{(-3+2)^{2} + (-1 -1)^{2} }$

radius = $\sqrt{(-1)^{2} +(-2)^{2}}$

radius = $\sqrt{5}$

radius = 2.24

The radius of this circle is 2.24

Cir = 2 x  pi * 2.24

Cir = 2 x 3.14 *2.24

Cir = 4.47 x pi

Cir = 14.04

Answer 2

Answer:

Answer:

Radius of Circle

radius  =\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }

radius  = \sqrt{(-3+2)^{2} + (-1 -1)^{2} }

radius = \sqrt{(-1)^{2} +(-2)^{2}}

radius = \sqrt{5}

radius = 2.24

The radius of this circle is 2.24

Cir = 2 x  pi * 2.24

Cir = 2 x 3.14 *2.24

Cir = 4.47 x pi

Cir = 14.04
