Find the exact circumference of a circle with diameter equal to 8 ft. I know the answer is 25 ft but the answers I have to choose from are 8, 16 or 64
hi help me please
I think there's an error in your answer choices.
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 8 ft.
To calculate the circumference, we'll substitute the value of the diameter into the formula:
C = π * 8 ft
Now, let's evaluate the expression:
C = 3.14 * 8 ft
C ≈ 25.12 ft
So, the exact circumference of the circle with a diameter of 8 ft is approximately 25.12 ft.
I agree with Ms Sue
Circumf = π(diameter) = 8π
= appr. 25.13
The "exact" answer is 8π
