Answer:
Using 3.14 as pi, the answer would be 56.52, and using just pi (as in the input on a calculator) would be 56.54867.
Step-by-step explanation:
The equation for circumference of a circle is C = πd, C representing the circumference and d representing the diameter. Since the equation shows the radius, the equation can also be C = 2πr, since the radius is half of the diameter. Multiply nine by two to get eighteen. 18 times 3.14 = 56.52.
Step-by-step explanation:
with 45 45 90 triangles which is what ACB is. the hypotenuse can be equalized with and the two legs have a length of x
so the side length for AB and BC is 6.
and since Triangle BCD is a 30 60 90 triangle.
the side lengths that would be corresponding would have the ratio of
x, , and 2x
so if 2x=6 x=3
then the value for x or BD is 3
Hope that helps :)
