Question

The blue segment below is a diameter of 0. What is the length of the radius of the circle

Answer 1

B. 5.1 units.

Explanation:

Givens

The diameter is

`d=10.2u`

Now, by definition, the radius is

`r=(d)/(2)`

Replacing given values, we have

`r=(10.2u)/(2)\\ r=5.1 u`

Therefore, the right answer is B.

Answer 2

Option (B) 5.1 units

Explanation:

Since the radius of the circle is half of its diameter and given the diameter of the circle is 10.2 units then the radius would be
`$ (10.2)/(2) = 5.1 units $`

Thus the answer.
