Step-by-step explanation:
Well the circumference of the circle is 2πr with is dπ
So the ratio is 8π : 8
Simplify:
π : 1
Hope this helps

To solve for x in one step:
Divide 80 by (-4/5)
Answer:
False
Step-by-step explanation:
Exponents do involve multiplication, but the power that a number is raised to is not the number it is multiplied by. Instead, exponents are used to determine how many times that number is multiplied by itself (to a certain extent, to explain better, it will have five "2's" being multiplied in this case). So, in the case of
, 2 is multiplied by itself 5 times, like so - 2×2×2×2×2 = 32. If we were to calculate 2×5, we would get 10, and
(32 is not equal to 10). Therefore,
is not the same as 2·5, and therefore the question is false.
