I'm assuming that when you say expanded form, you mean broken down into ones, tens, hundres and so forth.
so, 1203=1000+200+3
I don't know but I guess there is an answer
If a(2) = 0, then k=2. The product of the zeros is
(2)*(3)*(6)*(-3) = -108
The absolute value of the product of zeros of a(t) is 108.
Find total area
area=pir^2
d/2=r
12=d, 12/2=6=r
area=pi6^2=36pi, pi=3.14
area=113.04 square inches
22 per square inch
113.04 times 22=2486.88
rounded
2487 calories
Here is your solution.. hope it helps
