The cylinder is symmetric across the plane
, so we need only consider half of the cut-out region.
This region can be parameterized by
with
and
. Then the area of this half is given by the surface integral
Doubling this gives a total area of 72.
Yes.
0.32*76=24.32
If you need an explanation i can help
Answer:
I'm pretty sure it would cost $11.25 since 6 cookies would be $2.25 if you divide the amount for a dozen in half. I hope it was right!
Step-by-step explanation:
Let the variable "b" represent the number of bagels you buy
let the variable "R" represent the amount of money you have left
R = 25 - 1.25b
is your equation
then to find out after you bought 2 bagels
R = 25 - 1.25(2) = 25 - 2.5 = 22.5
do you would have $22.50 left on the card after you buy 2 bagels
