Question

the radius of a circle is 10 m. find its area to the nearest whole number. answer attempt 1 out of 2 a = m²

Explanation:

Step1: Recall area formula

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

Step2: Substitute radius value

Given $r = 10$ m, substitute into the formula: $A=\pi\times(10)^{2}=100\pi$.

Step3: Calculate numerical value

Using $\pi\approx3.14159$, $A = 100\times3.14159 = 314.159$.

Step4: Round to nearest whole number

Rounding 314.159 to the nearest whole number gives 314.

Answer:

314
