Question

the radius of a circle is 12.1 ft. find the circumference to the nearest tenth.
answer attempt 1 out of 2
$c = square$ ft

Explanation:

Step1: Recall the circumference formula

The formula for the circumference of a circle is $C = 2\pi r$, where $r$ is the radius of the circle.

Step2: Substitute the given radius

Given $r = 12.1$ ft, we substitute it into the formula: $C=2\pi(12.1)$.

Step3: Calculate the value

$C = 2\times3.14\times12.1= 75.988$ ft.

Step4: Round to the nearest tenth

Rounding $75.988$ to the nearest tenth gives $76.0$ ft.

Answer:

$76.0$ ft
