Question

if the area of a circular garden is 1886.56 sq metre ,fund it's circumference

Answer 1

Answer: 43.99114768 meters

How To: The formula for the circumference of a circle from the area is as follows:

c=2π⋅√(A/π)

where:

c is the circumference of the circle

A is the area of the circle.

To derive this formula:

Area: A = π • r2 .

Therefore we know that r= √(A/π)

We also know that circumference of a circle is a function of the radius

(C = 2 • π • r),

therefore, when we substitute for r:

c=2⋅π⋅√(A/π)
