Circumference of a circle =
They are all multiplied by each other
r = radius
we know our radius is 40
and...
= 3.14
so we would use this expression 3.14 x 40 x 2 As a added bonus ill solve it for you :P
3.14 x 40 x 2 = 251.2
The circumference of this ice skating rink is 251.2 feet
It’s b because if you do the math you can see that
Answer:
C and B.
Step-by-step explanation:
f(x) = 4 - x^2.
The degree of f(x) is 2, which means it is a quadratic graph. The coefficient of x^2 is negative, which means the curve is pointing downwards. The only curve that satisfies this is Graph C.
f(x) = 2^x + 5.
Notice that 2^x is positive for all real values of x. Therefore the answer is Graph B.

My other answer was was lacking (I also believe I should have furthermore edited it.), therefore I will attempt to explain the steps correctly this time. I don't know what exactly is requested nor what you are learning, but I suspect it would be combinations, factorials, and/or permutations, something along those lines. Firstly I figured out my answer using factorials.
FROM: F,R,O,M. This obtains 4 letters.
4! (1 x 2 x 3 x 4)= 24
I am unsure if this is what you are looking for though. I hope this helped a bit.
