Does a square with sides of 14" long have a greater area than a circle with a radius of 8"? (Use 3.14 for pie) Answer Yes or No
hram777 [196]

Answer: No

Step-by-step explanation:

Area of a square= side ^ 2

Since a side has been given as 14, we square the side given which is:

Area of square= 14 × 14 = 196

Area of a circle = π r^2

Since radius is 8, are will be

= 3.14 × 8 × 8

= 3.14 × 64

= 200.96

From the answers provided, the area of the circle is more than the area of the square.

The square does not have a greater area than the circle.
