What is the circumference and area of circle with a radius of of 5cm. Substitute 3.14 for pi
To find the circumference of a circle, you use the formula C = 2 * pi * r. Since the radius is 5 cm, the circumference would be:
C = 2 * 3.14 * 5
C = 31.4 cm
To find the area of a circle, you use the formula A = pi * r^2. Since the radius is 5 cm, the area would be:
A = 3.14 * 5^2
A = 3.14 * 25
A = 78.5 cm^2
Therefore, the circumference of a circle with a radius of 5 cm is 31.4 cm and the area is 78.5 cm^2.
