If a circle has a diameter of 4 inches, what is the circumference?

Answer 1

Evelyn Arboleda

#12.56# #"in"^2#

We know that the diameter is #4 # inches. The circumference can be got by

#color(blue)("Circumference"=pixx"Diameter"#

So,

#rarr3.14*4#

#color(green)(rArr12.56# #color(green)("in"^2#

Hope that helps!!! ☺•☻

#c=12.56#

The circumference of a circle is given by #c=pid# Where #c# is the circumference, #pi# is a number and its approximate value is 3.14 and #d# is its diameter. #implies c=pi4=3.14*4=12.56# inches #implies c=12.56# inches

The circumference of a circle can be found using the formula: ( C = \pi \times d ), where ( C ) is the circumference and ( d ) is the diameter.

Given that the diameter of the circle is 4 inches, substitute ( d = 4 ) into the formula: [ C = \pi \times 4 ]

Thus, the circumference of the circle is ( 4\pi ) inches.

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.
