A circular window has a diameter of 25 inches. It's approximation is 22/7
And your question is?
uhh i dnot kow how to do this plss help me
To find the circumference of a circle, you can use the formula C = πd, where C represents the circumference and d is the diameter of the circle. In this case, the diameter is given as 25 inches.
Using the approximation π ≈ 22/7, we can substitute the values into the formula to calculate the approximate circumference:
C = (22/7) x 25
C ≈ 22 x 25/7
C ≈ 550/7
C ≈ 78.57 inches
So, the approximate circumference of the circular window with a diameter of 25 inches is approximately 78.57 inches.
