Answer:

[tex]6.5\pi in[/tex] (B)

Step-by-step explanation:

The circumference of a circle is the length of its perimeter, and it is given by the equation

[tex]p=2\pi r[/tex]

where

r is the radius of the circle

In this problem, the radius of the circle is

[tex]r=3\frac{1}{4}in[/tex]

Which is equivalent to

[tex]r=\frac{3\cdot 4 +1}{4}=\frac{13}{4}=3.25 in[/tex]

Therefore, substituting into the equation, we find the circumference of the circle:

[tex]p=2\pi r=2\pi (3.25)=6.5\pi in[/tex]

So, option B.

Answer:

Hello!

To find the circumference of a circle you use the equation

C = 2 \pi rC=2πr

C is circumference

r is radius

Put in the values we know

C = 2 *\pi *3 \frac{1}{4}C=2∗π∗341

Multiply the 2 and the 3 1/4

C = 6.5 \piC=6.5π

The answer is C = 6.5
