The answer that goes in the blank is: 3
Note: The "pi" portion is already taken care of, so there's no need to enter it in the box.
============================================================
Explanation:
The distance around the entire circle is found by the circumference formula
C = 2*pi*r
where r is the radius.
In this case, r = 27, so,
C = 2*pi*r
C = 2*pi*27
C = 2*27*pi
C = 54*pi
The full distance around the circle is exactly 54pi units
We only want a small portion of it. We only want 20/360 = 2/36 = 1/18 of that distance
So multiply (1/18) by 54pi and we get...
(1/18)*(54pi) = (54/18)*pi = 3pi
So the length along the curve from A to B (or vice versa) is exactly 3pi units.
I did get 3(3-y)/2
Hope this helps you out
This is the concept of volume of solid figures, the volume of a given figure is given by:
volume=(base area)*(height)
In our case the base area will be given by the area of the trapezoid. Which is:
Area=1/2*h*(a+b)
height,h=x
a=x
b=2x
thus;
Area=1/2*x*(2x+x)=3/2x^2
Given that the height of the prism is 20 units, the volume will be:
V=(3/2 x^2*20)
V=30x^2 cubic units
The answer is 30x^2 cubic units
