Drag each tile to the correct box
Arrange the circles (represented by their equations in general form) in ascending order of their radius lengths.

Hope this helps!

Step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
