Answer = 18.84ft

To find the circumference of the circle, use the equation:

Circumference = pi x diameter

(Personally, I remember it as ‘cherry, pi, delicious’ (circumference, pi, diameter))

The diameter is given, so substitute that in the equation.

Circumference = pi x 6

pi x 6 = 18.84ft

Hope this helps :)

Simple drawing shows that measure interior angle at B is 25 degrees.

Easily seen from a drawing are that measure of angle CBD is 25 degrees, and measure of angle CAD is 65 degrees (which was already given).

Heres the plot formula!
