Answer: 5/6 inch/minute
Whenever you are working with a question of rate where two different quantities are being compared, the required units will indicate which quantity is to be divided by which.
In this case you want to know inches per minute.Therefore:

A regular octagon has 8 sides, so it would coincide exactly each time the vertices fall into the same places. In one full 360-degree rotation, any "selected" vertex would fall into all 7 other vertices one after the other, before going back to its original position. Therefore, there would be 8 times during the rotation that the octagon coincides with the preimage.
Answer:
(a) 4.00×10^7 m
(b) 5.10×10^14 m^2
(c) 1.083×10^21 m^3
Step-by-step explanation:
Put the given value of radius into the various formulas and do the arithmetic. Your scientific calculator can show you the results in scientific notation.
C = 2πr = 2π·6.37×10^6 m ≈ 4.00×10^7 m* . . . circumference
A = 4πr^2 = 4π(6.37×10^6 m)^2 ≈ 5.10×10^14 m^2 . . . area
V = (4/3)πr^3 = (4/3)π(6.37×10^6 m)^3 ≈ 1.083×10^21 m^3 . . . volume

* An early definition of the meter was 10^-7 times the distance from the North Pole to the Equator as measured through Paris, France.
Answer:
I haven't answered a question like this in a while but I'll just give it a shot:
I think it's 816.4
Step-by-step explanation:
h=13
20/2=10 so I believe that 10 would be the r (radius)
So then the equation could be:
S= 2(3.14)10×13
Multiply them all together and you get 816.4^^
