Q:
# Find the area of a circle with a circumference of 12.56 units

Accepted Solution

A:

Answer:12.56 square unitsStep-by-step explanation:The formula for circumference isC = 2πrOur circumference is 12.56. Using 3.14 for π, we have12.56 = 2(3.14)r12.56 = 6.28rDivide both sides by 6.28:12.56/6.28 = 6.28r/6.282 = rThe area of a circle is given by the formulaA = πr²Using 3.14 for π and our radius of 2, we haveA = 3.14(2²) = 3.14(4) = 12.56.
