Answer:
The length of the radius, r is 18 cm.
Step-by-step explanation:
If the radius of a circle is r, then the circumference of the circle is
It is given that circle O has a circumference of 36π cm.
Divide both sides by 2π.
Therefore the length of the radius of the circle is 18 cm.
I'd say 897.27cm². That's the vlosest answer that I see.
4^(-3) = 1/4^3 = 1/(4*4*4) = 1/64
which can also be written as 1/(2^6)
depending on your answer options.
