Answer: The diameter is 10cm

Explanation:


First, we divide 78.5/3.14 which = 25

Now, we find the square root of 25 to find the radius, which is 5.

The radius is 5cm, which means that the diameter is 10cm.


The diameter of the Ferris wheel is 10cm.


If we recalculate the area again with the diameter given, we can see that:


AREA = 3.14r2

AREA = 3.14 x 5 squared ( radius is half diameter )

AREA = 3.14 x 25 = 78.5
