Answer:
79.5 in ^3
Step-by-step explanation:
5 times 8 times 2.
40 times 2 equals 80.
2 times 1 times .25 equals .5
80-.5 equals 79.5 in^3
1 hour=3600 seconds
1 mile=5280 feet
87 miles/hr (1 hr/3600 sec)(5280 ft/mile)=127.6 feet/sec
Distance= Rate*time
d=127.6(12)=1531.2 feet (after 12 seconds)

Given


![[a,b] = [0,2]](https://tex.z-dn.net/?f=%5Ba%2Cb%5D%20%3D%20%5B0%2C2%5D)
Required
The volume of the solid formed
Rotating about the x-axis.
Using the washer method to calculate the volume, we have:

Integrate


Substitute values for a, b, f(x) and g(x)

Evaluate the exponents
