Answer:
2261.94671
Step-by-step explanation:
You must first find the circumference of the track. Using 2(pi)r.
Where pi=3.14... and r=radius
you can find the radius by dividing the diameter by 2, 120/2=60
Afterwards you input 60 into the equation. 60*(pi)*2= 376.99111843077515
Using that number you multiply it by 6 because she ran the circumference 6 times. 6*376.99111843077515 = 2261.94671
NOTE: The question may require you to simplify at certain times so answers may vary slightly. EX: pi = 3.14, Circumference = 377
Answer:
11 cakes
Step-by-step explanation:
so you know each cup can make 3 cakes so multiply that by 3 then add 2(from the 2/3 cups)
X + 17 +3x -15
x +3x = 4x
17-15 = 2
which becomes 4x +2 so it is true
Answer:
-2, 4, 36
Step-by-step explanation:
the equation should be:
(x+2)^2 + (y-4)^2 = 36
since the center is (-2, 3) and the radius is 6 units.
always remember:
C(h,k) = (x-h)^2 + (y-k)^2 = (radius)^2
