Answer:
8 cm
Step-by-step explanation:
volume of a cylinder is v=pi x r^2 x h
substitute in what we know
3785= pi x r^2 x 19
3785=59.69 x r^2
subtract 59.69 from both sides
3725.31=r^2
square root of 3725.31
61
square root of 61
= about 8

Answer:
(3, 140)
Step-by-step explanation:
If we have the equation 
, we can substitute the value 3 as 
to find the value of 
.
So we know that the total cost is $140.
To represent this as an ordered pair, we need to take note that the independent variable (x) is the one that we change to get the result (y).
We changed to get , so is the x and is the y.
So it's represented as (3, 140).
Hope this helped!
y=−4x^2. Should be your answer.
