Find the arc length of the semicircle the diameter is 8

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google
