The radius of a circle is 40 inches. What is its diameter?

A. 20 inches
B. 80 inches
C. 50 inches
D. 10 inches
That's Correct!
It's Wrong!

 It is given that:

Radius = 40 inches

We know that:

Diameter = 2 × Radius

Multiply the radius by 2 to find the diameter.

2 × 40 = 80

So, the diameter of the circle is 80 inches
