Answer:
The circumference of the circle in terms of π is 8π.
If π is approximated to 22/7, the circumference of the circle is approximately 25.14 cm.
If π is approximated to 3.14, the circumference of the circle is 25.12 cm.
Step-by-step explanation:
The circumference of the circle = 2*π*r
r = radius
r = d/2
r= 8cm/2 = 4cm
π = 3.14
The circumference of the circle = 2π(4)= 8π , so we have:
The circumference of the circle in terms of π is 8π.
Using pi = 22/7, we have:
The circumference of the circle = 2* 22/7 * 4 = 8* 22/7 = 25.14 cm, so we have:
If π is approximated to 22/7, the circumference of the circle is approximately 25.14 cm.
Using pi = 3.14, we have:
The circumference of the circle = 2* 3.14 * 4 = 8* 3.14 = 25.12 cm, so we have:
If π is approximated to 3.14, the circumference of the circle is 25.12 cm.
