Question

4.4 circumference and area of a circle
in the pacific northwest a red fox has a circular home range with a radius of about 718 meters. to the nearest whole number, about how many square meters are in a red foxs home range?
about m²

Explanation:

Step1: Recall area - formula for circle

The formula for the area of a circle is $A = \pi r^{2}$, where $r$ is the radius of the circle.

Step2: Substitute the given radius

We are given that $r = 718$ meters. Substitute $r = 718$ into the formula: $A=\pi\times(718)^{2}=\pi\times515524$.

Step3: Calculate the area

Taking $\pi\approx3.14$, we have $A\approx3.14\times515524 = 1618745.36$.

Step4: Round to the nearest whole number

Rounding $1618745.36$ to the nearest whole number gives $1618745$.

Answer:

$1618745$
