5.0×10^-1×10⁸
5.0×10⁷
Remember that the cone volume formula is 
, with r = radius and h = height. Using our information, we can form our equation as such: 
(I'll be keeping the answer in pi form.)
Firstly, solve the exponents:
Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3

You would multiply them
It is the same in this case
The expression would be n x k
It can be written as just nk though
