Q. Suppose the radius of a circle is 2 units. What is its circumference?Use 3.14 for π and enter your answer as a decimal.□ units
Formula for Circumference: To find the circumference, we use the formula C=2×π×r, where C is the circumference, π is approximately 3.14, and r is the radius.
Plug in Radius: Plug in the radius (2 units) into the formula: C=2×3.14×2.
Perform Multiplication: Perform the multiplication: C=2×3.14×2=6.28×2.
Complete Calculation: Complete the calculation: C=6.28×2=12.56 units.
