The length of a solid cylindrical cord of elastic material is 32 inches. A circular cross section of the cord has radius 1/2 inch. The cord is stretched lengthwise at a constant rate of 18 inches per minute. Assuming that the cord maintains a cylindrical shape and a constant volume, at what rate is the radius of the cord changing one minute after the stretching begins? Indicate units of measure.

-0..072 Inches Per Minutes

Step-by-step explanation:

Volume of a Cylinder, V =

Given l=32 Inches, r=0.5 Inches

V =

Since the Volume is constant,

After one minute,

Since the volume is constant

Therefore:

Therefore, the radius of the cord is reducing at a rate of 0.072 Inches per minute.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
