Find the diameter of the circle with a circumference of 50mm. Round your answer to the nearest tenth

A) 16.0 mm

B) 26.4mm

C) 8.4mm

D) 33.5mm

The answer is A, to get it you'll have to work backwards.

C = pi x d

so C divided by pi will get you the diameter

50 / pi = 15.91, rounded it should be 16.0 mm

A) 16.0 mm

Step-by-step explanation:

Use the formula C=2 x pi x r

d=2 x r

Solve for d

d = C/pi = 50/pi = 15.91549

And it says to round to the nearest tenth, so the answer is A) 16.0mm
