Answer:

Option B \(44\ cm\)

Step-by-step explanation:

we know that

The radius of the circle is half the diameter

Let

r-----> the radius of the circle

D----> the diameter of the circle

we have

\(r=22\ cm\)

\(r=\frac{D}{2}\)

Solve for the diameter

\(D=2r\)

substitute the value of r

\(D=2(22)=44\ cm\)
