Question

If circumference of a circle is 352 cm then find the radius and area of the circle.​

Answer 1

Ok lets do this. We know that the circumference formula is:
C = 2.pi.r
And we know that pi is 3,14 so lets find the radius:
352 = 2.3,14.r
352 = 6,28r
r = 56,05
Okay now we need find the area, the area of a circumference have this formula:
A = pi.r^2
So lets put the values:
A = 3,14.56,05^2
A = 3,14.3141,6
A = 9864,624

So the radius is 56,05 and the area is 9865,624
