Question

The center and a point on a circle are given. Find the circumference to the nearest tenth.

center:(5, −5);
point on the circle: (25, 10)

The circumference is about ?

Answer 1

Circumference ~ 157

Explanation:

Use the distance formula to find the radius. The radius is 25. Plug 25 into the formula 2(pi)r to get 50pi or about 157.

Answer 2

Answer: 50pi or about 157

Step-by-step explanation: Find the distance between the two points using the Pythagorean theorem, and since that is the radius double it to get the diameter, then multiply that by pi to get the answer. Hope this helps!
