Can someone please tell me how to do these problems
kow [346]
These are so easy, you won't believe it !

A negative exponent only means

       "Put all of this in the denominator, and make the exponent positive."

So    (any number)^negative power =

                     1 / (the same number)^(the same power but not negative) .

The first few problems on that sheet:

1).  5^-3  =  1 / 5^3

2).  6^-10  =  1 / 6^10

3).  (-2)^-5  =  1 / (-2)^5

Got it ?    You can do the rest of them now in about 2 minutes.

height = 10in

Substitute

V = π(11)²((10)

V = 3.14 * 121 * 10

V = 31.4*121

V = 3,799.4 cubic inches

Hence the volume of the cylinder is 3,799.4in³
