The circumference of the circle shown below is 42 centimeters. which expression gives the length in centimeters of?

To evaluate for the length of the diameter we proceed as follows:

Circumference is give by

C=πd

but

C=42 cm

hence plugging in the values and solving for d we get:

42=πd

=d=42/π=13.37 cm

Hence the diameter is 13 ... 37 cm

It will be the number of the circle divided by 360 multiplied by 42 pie
