Answer:
The answer is 15.9 centimeters. If you work backward with the formula 2pir = circumphrence, you get diameter *pi = 50. To find diameter, you divide 50 by pi and the answer is 15.9 centimeters.
Step-by-step explanation:
The diameter to the nearest tenth of a centimeter is mathematically given as
31.8cm, option D
What is the diameter?
Question Parameters:
Circle Q has a circumference of approximately 50 centimeters.
Generally, the equation for the circumference is mathematically given as
C=2\pir
Therefore
r=C/ \pi
r=50/3.14
r=15.9cm
Therefore,
d=2r
d=2*15.9
d=31.847
In conclusion, the diameter to the nearest tenth of a centimeter. is
31.8cm
