Círculo

A circle is a basic shape consisting of the points at a given distance from a given point on a plane.

The circumference U is the distance around a closed curve.

\( {\color{blue} {U}} = 2 \times \pi \times {\color{red} {r} } \)

U = Perímetro

r = Radio

\( {\color{red} {r}} = \frac{ {\color{blue} {U} } }{ 2 \times \pi } \)

r = Radio

U = Perímetro

\( {\color{blue} {U}} = \pi \times {\color{red} {d} } \)

U = Perímetro

d = Diámetro

\( {\color{red} {d}} = \frac{ {\color{blue} {U} } }{ \pi } \)

d = Diámetro

U = Perímetro

The region inside a circle.

\( {\color{OliveGreen} {A}} = \pi \times {\color{red} {r} }^{2} \)

A = Área

r = Radio

\( {\color{red} {r}} = \sqrt{ \frac{\color{OliveGreen} {A}}{\pi} } \)

r = Radio

A = Área

\( {\color{OliveGreen} {A}} = \frac{\pi}{4} \times {\color{red} {d} }^{2} \)

A = Área

d = Diámetro

\( {\color{red} {d}} = \sqrt{ \frac{4 \times {\color{OliveGreen} {A} } }{\pi}} \)

d = Diámetro

A = Área
