Question

test practice 6 find the circumference and area of a circle with radius 5 meters.

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle is $C = 2\pi r$. Given $r = 5$ meters, we substitute $r$ into the formula.
$C=2\pi\times5 = 10\pi$ meters.

Step2: Recall area formula

The formula for the area of a circle is $A=\pi r^{2}$. Substitute $r = 5$ meters into the formula.
$A=\pi\times5^{2}=25\pi$ square - meters.

Answer:

Circumference: $10\pi$ meters; Area: $25\pi$ square - meters
