Answer: 10 cm
Step-by-step explanation:
The circumference of the CD = 22\pi
We know that the formula of the circumference is:
Circumference = 2\pi r
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

Answer:

Step-by-step explanation:
Using k as the constant of proportionality.
The expression that expresses the relationship : p varies jointly with the square of d and the cube of u.
Varies jointly means that p will change as 'd' and 'u' will change together with respect to their powers.
We get the expression as:
