Answer:
A = pi r^2
Step-by-step explanation:
The formula for area of a circle is given by
A = pi r^2
1+1+1+1=4
2+2+2+2=16
3+3+3+3=?

Answer:
12 ; 12 dollars
Step-by-step explanation:
Data provided in the question:
Revenue function, R = 12x
R is in dollars
Now,
The slope can be found out by differentiating the above revenue function w.r.t 'x'
thus,
=
or
slope = 12
Now, for the second case of selling one more unit i.e x = 1, the revenue can be obtained by substituting x = 1 in revenue function
therefore,
R = 12 × 1 = 12 dollars
