Dirk ordered a circular pizza that was 16 inches wide. If dirk ate a quarter of the pizza how many square inches of the pizza did he eat?

4 inches. You divide 16 by 4 because a something in quarters is 4 pieces.

50.25

you have to find the area of the pizza first.

to do that you take half of the diameter 16

to get the radius 8

once you have the radius you square it 8*8 = 64

you than multiply it by pie 3.14

and get 200.95 or if you round 201

if you rounded you would get 50.25 if you didn't

than you would get. 50.24
