Answer 1

ANSWER

The radius is 2 feet.

EXPLANATION

The distance around the circular pit is 12.56 feet.

This means that, the circumference is 12.56.

We use the formula,

$C=2\pi \: r$

Substitute C=12.56 and π=3.14

$12.56 = 2(3.14)r$

Solve for r.

$r = \frac{12.56}{2(3.14)}$

Simplify

$r = 2ft$

Answer 2

Answer: 1.99 ft

Step-by-step explanation:

The formula for calculate the circumference of a circle:

$C=2r\pi$

Where r is the radius.

Based on the information given in the problem, you know that:

$C=12.56$

Substitute this value into the formula shown above and solve for the radius.

Then, this is:

$12.56=2r\pi\\r=\frac{12.56}{2\pi}\\r=1.99feet$
