Q. rCumference of CirclesFind the circumference of the bottle cap. U3.14 for π. Round to the nearest hundredth necessary. (Example 1)
Calculate Diameter or Radius: First, we need to know the diameter or radius of the bottle cap to calculate the circumference.
Use Circumference Formula: Assuming we have the radius r of the bottle cap, the formula for circumference C is C=2×π×r.
Plug in Radius Value: Let's say the radius of the bottle cap is 2cm. We plug it into the formula: C=2×3.14×2.
Perform Multiplication: Now, do the multiplication: C=4×3.14.
Calculate Final Circumference: After calculating, we get C=12.56cm.
Round to Nearest Hundredth: Finally, we round to the nearest hundredth if necessary, but since our answer is already at the hundredth place, no rounding is needed.
