Question

the radius of a circle is 7 ft. find its area in terms of $pi$. answer attempt 1 out of a $a=\text{blank}\text{ ft}^2$

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 $r = 7$ ft, substitute into the formula: $A=\pi\times(7)^{2}$.

Step3: Calculate the result

$(7)^{2}=49$, so $A = 49\pi$ ft².

Answer:

$49\pi$
