Answer:

Circle:

circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident.

$\large{ \boxed{ \tt{A = {\pi * r}^(2) }}}$

$\large {\boxed{ \tt{p = 2 * \pi * r}}}$

If the radius is 2 inches and

Use 3,14 for π So:

$\tt{ {A = \pi * {r}^(2) }}$

$\tt{A = (3.14 * 2 * 2)}$

$\red{ \boxed{ \bold{A = 12.56 {inches}^(2) }}}$
