Question

The radius of the larger circle is 10 cm. The radius of the smaller circle is 5 cm. What is the approximate area of the shaded region??

Answer 1

100*3.14= 314

25*3.14=78.5

314-78.5=235.5

Answer 2

235.5 because you solve area of the large circle and then do
(Larger circle) - (Smaller circle)
