Pizzas are sized by diameter. What percent increase in area results if Chantel's pizza increases from a 10-inch pizza to a 12-inch pizza?
please help :(
A 10-inches pizza has a 5-inches radius.
A 12-inches pizza has a 6-inches radius.
The area of (Pizza 1) is 5^2pi=25pi and the area of (Pizza 2) is 6^2pi=36pi
The percent of the increase is 36−2525∗100=44%
thank you!!!
