What is the arc length of arc cd in the circle below? circle a is shown with a radius labeled 15 feet and a central angle marked 45 degrees.

11.78feet

Step-by-step explanation:

Formula for calculating the length of an arc is theta/360° × 2πr

Given theta = 45°

radius (r) = 15feet

Area of an arc = 45/360×2π(15)

Area of an arc = 1/8×30π

Area of an arc = 30π/8

Area of an arc = 15π/4feet

= 11.78feet.

The length of the arc is therefore 11.78feet

answer: the answer is 23

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
