All you have to do is figure out the bases of the figure and use the 12 and 13 in your problems and you should be able to get the right answer.
No it is missing 10 yards in length
Answer: 6 miles
Step-by-step explanation:
The diameter is 2x the radius
2 x 3 = 6
(a) First find the intersections of

and

:

So the area of

is given by

If you're not familiar with the error function

, then you will not be able to find an exact answer. Fortunately, I see this is a question on a calculator based exam, so you can use whatever built-in function you have on your calculator to evaluate the integral. You should get something around 0.5141.
(b) Find the intersections of the line

with

.

So the area of

is given by


which is approximately 1.546.
(c) The easiest method for finding the volume of the solid of revolution is via the disk method. Each cross-section of the solid is a circle with radius perpendicular to the x-axis, determined by the vertical distance from the curve

and the line

, or

. The area of any such circle is

times the square of its radius. Since the curve intersects the axis of revolution at

and

, the volume would be given by
Answer:
if 135 calories represents 1/4 then a whole cup is 540 calories so two cups is 540 times 2 which is 1080
