The circumference of a circle is 14 π π cm. Find its radius, in centimeters

7 = r

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

14 pi = 2 * pi *r

Divide each side by 2 pi

14 pi/ (2 pi) = 2 * pi *r / (2 pi)

7 = r

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 : )

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
