D) 33.5mm

Respuesta :

Answer:

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

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
