Answer: 
Step-by-step explanation:
If a circle has a radius of 6, then the perimeter of the circle is 12pi, or about 37.68. A circle has 360 degrees. Thus, the arc takes up 48/360 of the circle. Thus, simply multiply 
to get 5.024 or 1.6pi.

Since the events are independent and can be reduced to two outcomes, we can solve it using the binomial formula.
$21 because 3$x$7(numbers of days in a week)is $21. I hope this helps :)
Using the shell method, the volume is
Each cylindrical shell has radius 
(the horizontal distance from the axis of revolution to the curve 
); has height 
(the vertical distance between a point on the 
-axis in 
and the curve ).
Compute the integral.
