Question

4 which of the following is the area of a circle with a radius of 3 cm? use 3.14 for π. 113.04 cm squared 9.42 cm squared 28.26 cm squared 29.55 cm squared skip 3/10 complete

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 and $\pi\approx3.14$.

Step2: Substitute radius value

Given $r = 3$ cm, substitute into the formula: $A=3.14\times3^{2}$.

Step3: Calculate the result

First, $3^{2}=9$, then $A = 3.14\times9=28.26$ $cm^{2}$.

Answer:

$28.26$ cm squared
