1/8 inch thick
inner diameter of 8.5
volume shell=volume total-volume shell
1/8=0.125
diameter/2=radius
radius inner=8.5/2=4.25
radiustotal=inner+outer=4.25+0.125=4.375
so
Vouter-Vinner=(4/3)pi4.375³-(4/3)pi4.25³
Vshell=(4/3)(pi)(4.375³-4.25)
Vshell=(4/3)(pi)(83.740234375-76.765625)
Vshell=(4/3)(pi)(6.974609375)
Vshell=9.299479166666666666666pi cubic inches
Vshell≈16.433536180619 cubic inches
Answer:
41 or 47
Explanation:
First, list all the prime numbers from 40 to 60.
They are 41, 43, 47, 53 and 59.
It says the difference between each digit is 3, so we have to subtract the smaller digit from the larger digit in our list of prime numbers above.
4-1=3
4-3=1
7-4=3
5-3=2
9-5=4
Both 41 and 47 have a difference of 3 between their digits. So your answer is 41 or 47.
