The formula for the area of a circle is A = πr^2. Which equation shows the formula in terms of r?

Respuesta :

gmany
[tex]A=\pi r^2\\\\\pi r^2=A\ \ \  |\text{divide both sides by}\ \pi\\\\r^2=\dfrac{A}{\pi}\ \ \ \ |\text{square root both sides}\\\\r=\sqrt{\dfrac{A}{\pi}}[/tex]

The formula in terms of r is [tex]\rm r = \sqrt { \dfrac{A}{ \pi}[/tex].

What is a Circle?

A circle is a round shaped figure whose all the points lie in one plane and the distance of the points on the circumference is constant from the center of the circle.

The formula of area of a circle is

A = πr²

The formula in terms of r is

r² = A/π

[tex]\rm r = \sqrt { \dfrac{A}{ \pi}[/tex]

Therefore, the formula in terms of r is [tex]\rm r = \sqrt { \dfrac{A}{ \pi}[/tex].
