Answer:
To find the minimum length of the belt, we need to calculate the circumference of the pants’ waist, which is a circle. The formula for the circumference © is:
C=πd
where ( d ) is the diameter. Given that the diameter of Phil’s pants is 49 centimeters, we can substitute ( d ) with 49 cm:
C=π×49 cm
Using pi (approx. 3.14159), we get:
C≈3.14159×49 cm
C is about 153.9611 cm
So, the minimum length that Phil’s belt should be is approximately 154 centimeters to fit around his new pants.
