Question

If the radius of a circle is 5 ft, what is the length of the diameter?

Answer 1

Answer: 10 ft

Step-by-step explanation:

diameter = 2r

diameter = 2(5)

diameter = 10 ft

Answer 2

10 ft

Step-by-step explanation:

When you have the radius, and you're trying to find the diameter, just multiply the radius by 2:

Diameter = Radius × 2

= 5 × 2

= 10 ft

Therefore, the radius is 10 ft.
