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

the image of (6, 9) under a dilation is (4, 6). the scale factor is

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
