Hello,I think you intended typing 16cm as the diameter of the circle in question. That's the value I worked with.
Answer:
The circumference of the circle is 50.24cm^2
Step-by-step explanation:
The circumference of a circle basically refers to the measure of the distance around the circle. In other words, if a circle was formed from a rope and later opened up to become straight, the length or the distance of the rope from one end to the other end is basically the circumference of that circle.
On the other hand, the radius of a circle is the measure of the straight line from the centre of any circle to its circumference.
The diameter is twice the value of the radius (2 × radius) and the radius = (diameter/2).
The formula for calculating the circumference of a circle is πd or 2πr.
Since the diameter in this case is 16cm and the radius is 16/2 = 8cm, π will be taken as 3.14, the circumference of the circle is then:
π × d = 3.14 × 16
= 50.24cm^2
Or 2πr = 2 × 3.14 × 8
= 50.24cm^2
