Andrew's dog Bubba has an exercise area behind the house. A stake in the ground has a 12 foot rope tied to it. The other end of the rope is fastened to Bubba's collar. If Bubba travels in a circular path around the stake. What is the largest Circumference allowed by the rope's length. Round to the nearest food.
75 feet
38 feet
452 feet
24 feet
what is the answer and why???

I seen that, I don't understand that though
C = pi * d
C = 3.14 * 24
C = ?
Which part don't you understand?
To solve this problem, we need to find the circumference of the circle that Bubba can travel. The circumference of a circle can be found using the formula: C = 2πr, where C is the circumference and r is the radius.
In this case, the rope is tied to a stake, acting as the center of the circle. The length of the rope is the radius of the circle. Given that the length of the rope is 12 feet, we can substitute this value into the formula:
C = 2πr
C = 2π(12)
C = 24π
Now, we need to round the result to the nearest foot. To do this, we need to find the approximate value of π. Most calculations use π as 3.14, so we can use that value:
C ≈ 24 * 3.14
C ≈ 75.36
Rounding 75.36 to the nearest foot, we get 75 feet.
Therefore, the largest circumference allowed by the rope's length is approximately 75 feet.
