Question

The formula for the circumference of a circle is C = 2LaTeX: \pi π r. If the circumference of the circle is approximately 32.7 inches, find the radius.

Answer 1

Answer:

$r=5.2\ in$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$C=32.7\ in$

assume

$\pi =3.14$

substitute the values and solve for r

$32.7=2(3.14) r$

$r=32.7/[2(3.14)]$

$r=5.2\ in$
