Question

question the radius of a circle is 3 cm. find its area to the nearest tenth. answer attempt 1 out of 2 a =

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 $r = 3$ cm, we substitute into the formula: $A=\pi\times(3)^{2}=9\pi$.

Step3: Calculate and round

Using $\pi\approx3.14159$, $A = 9\times3.14159=28.27431$. Rounding to the nearest tenth gives $A\approx28.3$ $cm^{2}$.

Answer:

$28.3$ $cm^{2}$
