Explanation:
To solve the math problem of how long it takes to mow the lawn using the circular motion method with a string attached to the pole, you'll need some additional information. Specifically, you'll need the radius of the circular lawn and the mowing speed of the string.
Once you have the radius (r) of the circular lawn and the mowing speed (v) of the string, you can calculate the time it takes (t) to mow the entire lawn using the formula:
t = (2 * π * r) / v
Where π is approximately 3.14159. Simply plug in the values for the radius and mowing speed to get the time it takes to mow the lawn.
