Hope this helps...:)

Answer 2

hey dear


here is your answer


Solution


Given


circumference of circle = 4 pi

Area of circle = ?


we use formula of area of circle


circumference of circle 2pir

2pir = 4

r = 4/2

r = 2

we use formula of area of circle


A = pir^2

A = 22 /7 * 4 *4

A = 352 / 7


hence area of circle

50.2


hope it helps

thank you
