Answer:
63
Step-by-step explanation:
First we need to find the area of each pizza in square inches with pizza with the round shape, then calculate the difference.
The formula of area of circle is:
Area = π
As we know, medium pizza has 12 inch diameter and small pizza has 8 inch diameter.
- <u>For 12 inch diameter, radius = 6
</u>
A = π = 36π
- <u>For 8 inch diameter, radius = 4
</u>
A = π = 16π
Difference of the two area: 36π - 16π = 20π
by putting the value of π, the difference is
A=20 * 3.14 => 63
Answer:
12.36%
Step-by-step explanation:
For year 1:
T(1) = 1000(1.06)¹
T(1) = 1060
After two years, t = 3
T(3) = 1000(1.06)³
T(3) = 1191.06
The percent of the increase is
[(T(3) - T(2)/T(2)]*100%
[(1191.06 - 1060)/1060]*100%
12.36%
