Let's say we have a circle with a radius of 14 inches. What is the circumference of this circle in inches? Round your answer to the nearest whole number.

Question

anonymous · Answer

circumference of circle is 2pi*r

anonymous · Answer

C = 2*PI*R --> R is the radius, and Pi is the constant approximately 3.14. Plug in the given values in to the equation and solve.

C = 2*Pi*(14)
   = 28*Pi
   = 88 inches (approximately, rounded off to the nearest whole number)

if your dealing with circles you should memorize some formulas
Circumference = 2pi r = diameter(pi)
Area = (pi) r^2
these will come in handy for circle problems
