What is the approximate circumference of a circle with a diameter of 300 feet

almond37 [142]

Circumference = 2πr

Since you know the diameter is 300, you divide it by 2 to find the radius. Therefore, the radius is 150.
Now plug it into the formula: C = 2(3.14)(150)
C = 942

Answer: Circumference is 942 feet
