Question

The circumference of a circle is 31.4 cm. Find the radius and the area of the circle.


Answer 1

circumference of circle =2pieR
31.4=2pieR
from here u can calculate the radius as well as area

Answer 2

Circumference of circle=31.4cm
∴  2πr=31.4
    2*3.14*r=31.4
             r=31.4*3.14
             r=10
Hence radius is 10cm
