Question

sorry but you have not take out the area of the circle but your radius answer is correct ​

Answer 1

Answer:

area of a circle is π r×r

Step-by-step explanation:

22/7 × 40.09×40.09

=5046.63 cm 2

Answer 2

Answer:

Hope it will help you

Step-by-step explanation:

circumference of a circle = 2πr

252 cm = 2 * 22/7 * r

(252 *7)/ 44 = r

1764/44 = r

40.09 = r

∴radius = 40.09 cm

Area of circle = πr²

                      =22/7 * 40.09 * 40.09

                      = 22*5.727*40.09

                      =5051.099cm ²
