If the diameter of a circle is 18 feet, which is closest to the circumference?
A.
56.52 feet
B.
9 feet
C.
5.73 feet
D.
28.26 feet
A.56.52 feet
56.52 feet :]
whats the answer
To find the circumference of a circle, you can use the formula C = πd, where C represents the circumference and d represents the diameter of the circle.
In this case, the diameter is given as 18 feet, so plugging this value into the formula gives us C = π * 18. To find the closest value to the circumference, we need to calculate the result.
The value of π is approximately 3.14, so multiplying it by 18 gives us C = 3.14 * 18 = 56.52 feet.
Therefore, the closest value to the circumference of the circle with a diameter of 18 feet is 56.52 feet.
The correct option is:
A. 56.52 feet
circumference = pi * Dia. = 3.14 * 18 =
D ÷ π = circumference.
Also,
D = Diameter, Henry called it Dia.
π = pi, the pi number = 3.14.
