Find the exact circumference of a circle with diameter equal to 8 ft.
8 ft.
16 ft.
64 ft.
what equation would u use?
C = pi * d
Find the length of an arc of an 8" radius circle if the arc measures 45°.
3.14
To find the circumference of a circle, you can use the equation 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. So, you can substitute this value into the equation to find the circumference.
Using the equation C = πd, you would have:
C = π(8 ft)
To get the exact circumference, you would need to use the value of π (pi). Pi is an irrational number approximately equal to 3.14159, but to get the exact circumference, we need to use its exact value.
So, the exact circumference of a circle with a diameter of 8 ft is:
C = 3.14159(8 ft)
C ≈ 25.13272 ft
