Question

If BC=5 in and AB=12in. Find the exact circumference of the circle.

Answer 1

EXPLANATION

We can get the circunference of the circle by applying the Pythagorean Theorem as shown as follows:

$\text{AC}^2=AB^2+BC^2$

Repalcing terms:

$AC^2=12^2+5^2=144+25=169$

Aplying the square root to both sides:

$AC^{}=\sqrt[]{169}=13\text{ inches}$

The circunference is 13 inches.
