The diameter of a circle is 4 cm. Which equation can be used to find its circumference? C = pi times 2 C = pi times 4 C = StartFraction pi times 4 over 2 EndFraction C = StartFraction pi times 4 over 4 EndFraction

Respuesta :

Answer:

Circumference is 12.52 cm

Step-by-step explanation:

R= D/2=2

C=2piR

C=2(3.14)*2=12.52

Answer:

A circle with diameter of StartFraction 7 over 2 EndFraction centimeters.

The radius is 7/4  cm.

The circumference in terms of π is π 7/2 cm.

Using 3.14 for π, the approximate circumference of the circle is  11.0cm.
