What's the circumference of a

Mathematics
1 answer:

8 0

Answer:

C = 31.4 inches

Step-by-step explanation:

To find the circumference of a circle, the formula is d(pi), or 2r(pi)

We are given the radius, so let's just plug in the number:

2(5)(pi)

So our circumference would be 10pi

We have to get an approximation here, so we would do 10(3.14)

That would be 31.4 inches

I hope this helps, let me know if you have any questions.

Suppose the radius of a circle is 3 units what is the circumference
HACTEHA [7]

Answer:

6\pi or approximately 18.85 units

Step-by-step explanation:

The formula for finding the circumference of a circle is C=2\pi r, where C = circumference and r = radius. In this case, r=3, so after plugging that into C=2\pi r, we get:

C=2\pi r\\  = 2*\pi *3\\=6\pi

Since \pi is approximately 3.1415, 6\pi =6*3.1415=18.849, which rounds to 18.85. Therefore, the circumference of the circle is 6\pi, or approximately 18.85 units. Hope this helps!
