Answer:
- radius: 15 ft
- diameter: 30 ft
- circumference: 30π ft
Step-by-step explanation:
The area is given in terms of the radius as ...
A = πr^2
so we can find the radius as ...
r = √(A/π)
For your circle, the radius is ...
r = √(225π ft^2/π) = 15 ft
The diameter is twice the radius, so is ...
d = 2r = 2·15 ft = 30 ft
And the circumference is π times the diameter:
C = πd = π·30 ft = 30π ft
Answer:
11 function 12 not a function
Step-by-step explanation:
11 doesnt hit with any line 12 does
I had homework on this today lol
First, add 2 to both sides. It would then be 5x = 3x + 10. Then subtract 3x from both sides and you would end up with 2x = 10. Divide 2x by 2 and the 10 by 2. The answer is x = 5.
Answer:
3
Step-by-step explanation:
Circumference =
, where r is radius, and d is diameter
d=113/3.14=35.987, which is approximately 36
At 12 yards per hour, it will take 36/12=3 hours
