Question

Estimate the diameter of a circle with a circumference of 56 feet.

Answer 1

Circumference of a circle = \(2\pi r\) where r is the radius of the circle.

Since, 2*r = diameter of the circle

So , Circumference of a circle = \((2r) \pi = \textbf{Diameter} \times \pi\)

Since, circumference = 56 feet.

Therefore, 56 = diameter * \(\pi\)

Thus, diameter = \(\cfrac{56}{\pi}\)
