What is the circumference of a circle if the diameter is 1.6?

Answer 1

Circumference #= 5.0#

Formula for circumference of circle is #pid# #color(white)("XXXX")#where #d# is the diameter, and #color(white)("XXXX")pi# (approximately #3.14159#) is a standard constant.

With a diameter of #1.6# #color(white)("XXXX")#circumference #= pi*1.6#

#color(white)("XXXXXXXXXXXX")~~3.14159*1.6#

#color(white)("XXXXXXXXXXXX")~~ 5.02654#

Since the diameter is only given to 2 places of accuracy, the computed average should be rounded to 2 places as well: #color(white)("XXXX")#circumference #= 5.0#

The circumference of a circle can be calculated using the formula C = π * d, where C is the circumference and d is the diameter of the circle. Given that the diameter is 1.6, substitute this value into the formula to find the circumference. Therefore, the circumference is approximately 5.03 units.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
