Find the area of a circle given C = 4*3.14 give an answer in terms of 3.14

Answer 1

We can use the formula C = 2πr, where C is the circumference and r is the radius. Solving for r, we get:

r = C/2π

Substituting C = 4*3.14, we get:

r = (4*3.14)/(2*3.14) = 2

Now that we know the radius is 2, we can use the formula for the area of a circle:

A = πr^2

Substituting r = 2, we get:

A = 3.14*(2^2) = 12.56

Therefore, the area of the circle is 12.56 square units, in terms of 3.14.
