Question

If the diameter of a circle is 12 units what is its radius​

Answer 1

Answer:

First you need to find the radius, the key term to find the radius is diameter=2⋅radius ; therefore the radius r is 122=6 inches. To find the area of a circle, you need to use the formula A=π⋅r2 ; therefore the area A is π⋅62≈113 square inches.

Answer 2

Answer:

Diameter = 12 units

Radius = Diameter/2

= 12/2

= 6 units

So , the radius is 6 units.
