PLEASE HELP ME

Step-by-step explanation:

To get the length of the arc, we are going to use the formula for calculating the circumference of a semicircle.

Circumference of a  semi circle = πd/2

Given

Diameter d = 8

π = 3.14

Substitute;

C = 3.14(8)/2

C = 3.14 * 4

C = 12.56

Hence the the length of the arc is 12.56

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

d
