Question

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?

Answer 1

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

Answer 2

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
