Step-by-step explanation:
Given: The circumference of a circle can be found using the
To solve the above equation for radius of the circle 'r', first divide on both sides of the equation, we get
Hence, the formula to calculate radius 'r' is the circle will be :
Answer:
Area=πr²
area= π(12)²
area=452.4cm²
