Hello,
Answer C : always Al Kashi
1) 16x16= 256ft
16x3x4= 192ft
add them together
256+192= 448ft2 (2 is the little number at the top next to the unit)
2) 3.14x7(2)= 153.86ft2
and i’m not sure on the other part SORRY
Given:
the design is to be rotated about the line x = 1 to produce the shape of the urn.
To generate a design for the urn, we need to draw a vertical line at x = 1, this will be our axis of rotation (or the basis for our mirror). We will use the mirror principle in making our design. So we will either draw half the shape of the urn at the left or right side of the axis of rotation.
Since 4 pounds of flour costs $2.60, we have that:

Where x is the amount of flour you get for 1 dollar.
We can rewrite the expression above as follows:

Then, we get 1.54 pounds of flour per dollar
