Question

What is the circumference of the circle shown below? (Round your answer to the nearest tenth)

Answer 1

Answer:

D. 46.5

Step-by-step explanation:

The formula to find the circumference of a circle is: 2πr

2(π x radius)   or  π times the diameter.

The radius is 7.4

7.4 x 2 = 14.8

14.8π ≈ 46.5

Answer 2

Answer: D. 46.5 units

Step-by-step explanation:

From the given picture it can be seen that using the definition of a radius of circle, the radius of the given circle = r = 7.4 units

Now, we know that the circumference of a circle is given by :-

$\text{Circumference}=2\pi r=\\\\\Rightarrow\ \text{Circumference}=2\pi(7.4)=46.4955712731\approx46.5\text{ Units}$

Therefore, the circumference of the given circle = 46.5 units.
