Question

What is the diameter of the circle (write only the numeric answer no units)

Answer 1

Answer:

The circumference is 15.996 cm

Explanation:

Given the area of the circle as

$200.96cm^2$

This means:

$\begin{gathered} \pi r^2=200.96 \\ r^2=\frac{200.96}{\pi}=63.97 \\ \\ r=\sqrt{63.967}=7.998 \end{gathered}$

Now that the radius has been obtained, the diameter of a circle is twice the radius, therefore

$\begin{gathered} c=2\times7.998 \\ =15.996cm \end{gathered}$
