Answer:
260
Step-by-step explanation:
When x represents whole numbers less than 200, the function
f(x) = 2x - 20 .......... (1)
represents the profit earned from selling x carnations for a school fund-raiser.
Therefore, the profit earned from selling 140 carnations for the school fund-raiser will be given by the equation (1) as
f(140) = 2(140) - 20 = 280 - 20 = 260.
Therefore, 260 is the value of f(140). (Answer)
and 9 are the squares of, respectively, 
and 3.
So, using
we have
C=πr²
c=22/7*28²
c=22/7*784
c=(22*784)/7
c=22*112=2464
