Find the area of a circle with a circumference of 6.28 unitesz

Anni [7]

Answer:

3.14 square units

Step-by-step explanation:

Circumference of a circle = 2πr

2πr = 6.28

r = 6.28/2π

r = 3.142/π

Area of a circle = πr^2

slot in the value of r

Area of the circle = π( 3.142/π)^2

" = π(9.87/ π^2)

" = 9.87/π

π = 3.14

Area of a circle = 9.867/ (3.14)

" = 3.14 square units
