Find the circumference and area of a circle with a radius of $5 ext{ cm}$.

To find the circumference of a circle, we use the formula:

$C = 2\pi r$

Plugging in the radius of 5 cm:

$C = 2 \pi (5) = 10 \pi \approx 31.42 \text{ cm}$

To find the area, we use the formula:

$A = \pi r^2$

Plugging in the radius of 5 cm:

$A = \pi (5)^2 = 25 \pi \approx 78.54 \text{ cm}^2$

The circumference of a circle is given by:

$C = 2 pi r$

With radius 5 cm:

$C = 2 pi imes 5 = 10 pi$

Approximating $pi$ as 3.14:

$C approx 10 imes 3.14 = 31.4 ext{ cm}$

The area is given by:

$A = pi r^2$

With radius 5 cm:

$A = pi (5)^2 = 25 pi$

Approximating $pi$ as 3.14:

$A approx 25 imes 3.14 = 78.5 ext{ cm}^2$

Circumference:

$C = 2 pi imes 5 = 10 pi approx 31.4 ext{ cm}$

Area:

$A = pi imes 5^2 = 25 pi approx 78.5 ext{ cm}^2$
