Answer:
C
Step-by-step explanation:
Volume = πr²h
r = 2.5 inches plus 1inch cushon thickness = 3.5 inch radius.
V = 3.142*3.5²*13
V = 500.56in³
0=65-10t-5t^2
now what you want to do is multiply a and c
-5(t^2+2t-13)
Now just find the zeros

He bought x pens for 1.05 each and you have to add the $4 shipping fee to it
Hope this Helps
The area of a circle is r^2*PI -> d = 10inch -> r = 5inch --> r^2 * PI = 5 * 5 * 3.14159 = 78.54 in^2
