Multiplying binomial and polynomials can be easy as long as you follow the steps for example:
Let's say you were multiplying 3x-3 and x+2
(3x-3)(x+2)
remember FOIL
OR think about it like this(see attatchment)
3x^2 + 3x -6 is what you should get

Solve
Start by converting the mixed number to improper fraction

Convert the division to muliplication



Hence:

1/3(9)(10) = 30in^2
Hope it helps, you just have to plug in the values into formula given
Answer:
The next term is 64, a is 2, and the common ratio is 2.
Step-by-step explanation:
Look at what's happening from each number to the next. What do you need to do to get from 2 to 4, or 4 to 8? Multiply by 2. That's your common ratio. To get the next number in the sequence, multiply the last number by the common ratio of 2. 32 x 2 = 64, so the next number in the sequence is 64. "a" is just the very first term, meaning it's 2.
I believe its
40*2*1/2*pi meters per second
which is just
<h2><u><em>
40pi meters per second</em></u></h2>
if you need it simplified, its
<h2><u><em>
125.66370meters per second</em></u></h2>
