Answer:
Domain = [0 , +∞)
Step-by-step explanation:
since r is the radius of a circle
Then
r must be a positive number.
Then
r ≥ 0
NOTE : if r = 0 ,then the circle reduces to a point .
Step-by-step explanation:
Below is an attachment containing the solution
√324 * √75 = √24300 = 90√3
so
90√3 / 9 = 10√3
answer is
D. last one 10√3 irrational
4a3b5 − 16a5b2 + 12a2b3 = 4 * a^2 * b^2 * ( a*b^3 - 4 * a^3 * + 3 * b^3) (:
Answer:
3d
Step-by-step explanation:
A regular hexagon has six equivalent triangles, each triangle having one side of that of the hexagon. if the diameter of the circle in which the hexagon is inscribed is d , then its radius will be
this radius also happens to be one of the side of the equivalent triangle whose one side is also the side of hexagon. since length of one side of hexagon is
the circumference of the hexagon will be
