Find the diameter of a circle with a circumfrence of 50 mm. Round your answer to the nearest tenth.
A. 16.0mm
B. 26.4mm
C. 8.4mm
D. 33.5mm
Is the answer C?
Thank you
To find the diameter of a circle, you can use the formula:
diameter = circumference / π,
where π (pi) is approximately 3.14159.
In this case, you have a circumference of 50 mm. Using the formula, you can calculate the diameter:
diameter = 50 mm / 3.14159 ≈ 15.92 mm.
Rounding this to the nearest tenth, the answer is approximately 16.0 mm, so option A is the correct answer.
Therefore, the correct answer is A. 16.0 mm.
C = 2πr
50 = 2πr
r ≈ 8.0 mm
d = 2r = 2(8.0) = 16.0 mm
You are looking for the diameter, not the radius. The correct answer is A.
Diameter=circumference/PI
No, not C.
