What is the approximate circumference of circle shown below?
a.21.7 cm
b.43.3 cm
c.86.7 cm
d.51.3 cm
me !

B. 43.3 cm

Step-by-step explanation:

The formula for the circumference of a circle is if you want it in terms of the radius but you can also say the circumference is if you want it in terms of the diameter since you know the radius is twice the diameter.

So we are actually given the diameter which is 13.8 cm.

So the Circumference is just pi times that.

So I'm going to put pi times 13.8 in my calculator and select the closest answer.

13.8*pi=43.35 cm.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
