To find this answer you need to find the area of the whole cake and divide it by 8. To find area of a circle, you need the formula (pi)*r^2. The radius is the diameter divided by two. Your final formula would be (pi)*8^2. This is approx. 201.06 in^2. Divide this number by 8, and you have your answer. I got 25.13 in^2.
There are 16 ounces in a pound. 16 times 2.5 equals 40.

Answer:
5%
Step-by-step explanation:
To find the increase, we must do 1906 - 1815 = 91
To find the percentage increase, we need to do 91/1815.
91/1815 to the nearest ten-thousandth is 0.0501
Percent = 100 * decimal
0.0501*100 = 5.01%
Rounded to one decimal place = 5.0 = 5
