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

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
