Question

Find the diameter of each circle given the radius.

radius=6cm
radius=5cm
radius=9cm
radius=8cm
radius-1.5cm
radius=18cm
radius=4cm

Answer 1

1. 12cm.

2. 10cm.

3. 18cm.

4. 16cm.

5. 3cm. (or -3 if your question was negative.)

6. 36cm.

7. 8cm.

Step-by-step explanation:

To find the radius of a circle, simply divide the diameter by 2.

With this being said we can just add on top of the given radius.

Example:

The given radius is 5cm. What is 5cm + 5cm? 10cm.

Thus, getting our answer.
