Answer:
40π feet
Step-by-step explanation:
Using the diameter of a circle you can find the circumference much easily than the radius. To find circumference with diameter you would do π×d or in this case π*40 which would give you the answer 40π.
Answer:Julios's number is 31
suppose: Julios's number is x
because Julio says, "If you subtract 13 from my number and multiply the difference by -3, the result is -54 "
=> we have: (x - 13).(-3) = -54
<=> x - 13 = (-54):(-3) = 18
<=> x = 18 + 13 = 31
<=> x = 31
Step-by-step explanation:
Answer:
(2, -3)
Step-by-step explanation:
Compare the given (x-2)2+(y+3)2=9 to the standard equation
(x - h)^2 + (y - k)^2 = r^2.
It becomes obvious that h = 2, k = -3 and r = 3.
The center of this circle is (h, k): (2, -3).
