Answer:

249.68 square centimeters

Step-by-step explanation:

Let C and A be the circumference and the area of the circle respectively.

C = 2πr

56 = 2 × 3.14 × r

56 = 6.28 × r

Divide both sides by 6.28

r = 56/6.28

r = 8.9172

A = πr^2

A = 3.14 × (8.9172)^2

= 249.68 square centimeters

Therefore, area of the circle is 249.68 square centimeters
