The diameter of a circle is 7cm. Find the circumference of the circle if pie = 22/7
The formula for the circumference of a circle is:
C = πd
Where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and d is the diameter of the circle.
Given that the diameter of the circle is 7 cm and π = 22/7, we can substitute these values into the formula and find the circumference:
C = πd C = (22/7) x 7 C = 22 cm
Therefore, the circumference of the circle is 22 cm
