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.
