Which size(s) of pizza should he order? Why?

Answer 1

a) we know, circumference of circle = 2πr
i)Circumference of small pizza with radius of 8 inches; = 2*3.14*8 = 50.24 in.²
ii)Circumference of medium pizza with radius of 10 inches; = 2*3.14*10 = 62.8 in.²
iii)Circumference of large pizza with radius of 12 inches; = 2*3.14*12 = 75.36 in.²

b) we know, area of a circle = πr²
i)Area of small pizza with radius of 8 inches;= 3.14 * 8²= 200.96 in.²
ii)Area of medium pizza with radius of 10 inches = 3.14 * 10² = 314 in.²²
iii)Area of large pizza with radius of 12 inches; = 3.14*12² = 452.16 in.²

c) Joey should order pizzas of larger size 'cause he is very hungry & it will be most helpful for him 'cause of larger area.
