Find the diameter of a circle with a circumference of 50 mm. Round your answer to the nearest tenth.
• 15.9 mm
• 26.4 mm
• 8.4 mm
• 33.5 mm
The formula to calculate the diameter of a circle is D = C / π, where C is the circumference of the circle and π is approximately 3.14159.
Given that the circumference is 50 mm, we can plug this into the formula:
D = 50 / π
D ≈ 50 / 3.14159
D ≈ 15.9 mm
Therefore, the diameter of the circle with a circumference of 50 mm is approximately 15.9 mm, rounded to the nearest tenth.
Answer: 15.9 mm
