Answer:

440m^2

Step-by-step explanation:

15400/(22/7)=4900, which is r^2, so r=70. Now we can find the circumference by doing 22/7*2*70, which is 440.

Find the radius of the circle:

Area of a circle = pi x r^2

15,400 = 22/7 x r ^2

Divide both sides by 22/7

4900 = r^2

Take the square root of bothe sides:

R = 70

The radius of the circle is 70 meters.

now find the circumference:

Circumference = 2 x pi x radius

Circumference = 2 x 22/7 x 70

Circumference = 440 meters

answer: 440 meters
