If d=9cm, find the circumference

The circumference is the diameter times PI

The exact circumference would be 9PI cm

The approximate circumference would be 9 x 3.14 = 28.26 cm

Step-by-step explanation:

d = 9cm

Circumference = πd  

                         = 3.14*9 = 28.26 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.
