Answer:
circumference=13π cm (see below if you need π approximated)
Explanation:
Hi there!
The formula for the circumference of a circle is given as 2πr, where r is the radius and π is pi
we are given that the radius of the circle is 6.5 cm
substitute what we know into the equation:
circumference=2πr
circumference=2π*6.5
circumference=13π cm
some places will accept the answer as 13π, but others ask to have π substituted, usually as 3.14 or 22/7
if you need π substituted as 3.14, the answer will be 40.82 cm
if you need π substituted as 22/7, the answer will be about 40.86 cm
Hope this helps! :)
