Solution:
Given:
Circumference of Circle, 62.8cm
Since,
Circumference of Circle=2πr
Therefore,
2*22/7*r = 62.8 cm
=>2*3.14*r = 62.8 cm
=>2*r = 62.8/3.14 cm
=>2*r = 20cm
=> r = 20/2=10cm
Thus, radius of given Circle is 10 cm.
We know that:
Area of Circle= π*r*r
So, the area of given circle=
22/7*10cm*10cm
=> 3.14*10cm*10cm
=> 314cm²
Ans: Hence the area of given circle of circumference 62.8 cm is 314cm².
