The circumference of a circle with a diameter of 37.6 m is 118.1 m to one decimal place, calculated using the formula C = π × d.
The circumference of a circle can be calculated using the formula:
C = π × d
Where C is the circumference, π (pi) is approximately 3.1415927, and d is the diameter of the circle.
For a circle with a diameter of 37.6 meters, the circumference is calculated by multiplying π with the diameter:
C = 3.1415927 × 37.6 m
Using a calculator:
C = 118.076 meters (unrounded)
However, since the diameter is given to three significant figures, our final answer for the circumference should also be to three significant figures:
Therefore, the circumference is 118 meters to three significant figures or rounded to 118.1 meters to one decimal place.
