Answer 1

can u please help me!!!

Answer 2

The circumference of a circle (lets call it c) is given by c = pi*d with d the diameter. So, for c = 50, the diameter is 50/pi which is 15.9, in which case i guess 16.0 is be the answer.

Answer 3

okay thank u TimS.

Answer 4

is* not "is be" :)

Answer 5

so it 26.4 mm

Answer 6

Did you understand the calculation? The number pi is equal to approximately 3.14. Then, \[\frac{ 50 }{ 3.14 } \approx 16\]

Answer 7

The number pi is defined as the ratio between the circumference and the diameter of a circle.
