Use the formula
C = πr2
-3 is the answer.... i think
Answer:
V = πr²h
Step-by-step explanation:
X=1, y=4
Substitute 4x in for y in the second equation and you get 5x=5. Divide out 5 and you get x=1. Then, you can plug 1 in for x into either equation and solve for y.
Answer:
The two positive integers are 30 and 30
Step-by-step explanation:
Let
x------> the larger positive integer
y-----> the smaller positive integer
P----> the product o the two positive integers
we know that

-----> equation A
----> equation B
substitute equation A in equation B

This is the equation of a vertical parabola open downward
The vertex is a maximum
The y-coordinate of the vertex is the largest possible product
Using a graphing tool
The vertex is the point (30,900)
That means------> For
The largest possible product is 
and
------> 
therefore
The two positive integers are 30 and 30
