Answer:
31.42ft
Step-by-step explanation:
diameter = 10
radius = diameter ÷ 2
r = 10 ÷ 2
r= 5
Circumference = 2(pie)(r)
= 2(22÷7)(5)
= 31.42ft
The rule seems to be to add 8. 10+8=18+8=26+8=34+8=42. I hope this helps!

Hello from MrBillDoesMath!
Answer: The cylinder on the left has 4 times the volume of the cylinder on the right.
Discussion.
The volume of a cylinder of height "h" and radius "r" is given by
PI * r^2 * h (r^2 signifies r squared)
(Think of this formula as the area of the circle or radius r multiplied by the height the circle is pushed "up" to create the cylinder)
The volume of the cylinder on the left is: Pi * 4^2 * h = 16 Pi *h
The volume of the cylinder on the right is: Pi * 2^2 * h = 4 Pi *h
As 16/4 = 4, the cylinder on the left has 4 times the volume of the one on the right.
Thank you,
MrB
