Question

A can of cat food has a diameter of 8 cm. Which measurement is the best estimate for the circumference of the cat food inside the can?

Answer 1

ok The circumference of a circle is 2πr or πD if diameter is given.

The answer is 25.13 cm

Explanation:

Now method 1:

C=2πr

So finding for radius in this equation=diameter/2

8/2=4 cm

So now 2 × 22/7 × 4

176/7=25.13 cm

OR

C=πD

22/7 × 8

176/7=25.13 cm
