Jamie has an old cd that she wants to use for an art project. the circumference of the cd is 22π 22 π cm and she would like to cut from one side to the middle but leaving one cm. what would be the measure of the cut portion? 22 cm 10 cm 20 cm 11 cm

10 cm

Step-by-step explanation:

The circumference of the CD =

We know that the formula of the circumference is:

Circumference =

We will substitute the value of circumference to find the radius:

22 pi = 2 x pi x r

r = 11

Therefore its radius will be 22 / 2 = 11 cm

Jamie wants to cut the CD from the middle of the CD to one side but leaving one cm. To find the measurement of the cut portion, we will subtract 1 from 11 to get:

11 - 1 = 10 cm
