Acircle has a radius of 13 inches. which equation can be used to find the diameter of this circle? d=2π(13)

d=12(13)

d=2(13)

d=132

Step-by-step explanation:

We know that, the diameter of a circle is twice of the radius of the circle.

Therefore, if r is the radius of the circle, then diameter of the circle will be :-

Given: A circle has a radius of 13 inches.

Therefore, the diameter of the given circle will be :-

Hence, the equation which can be used to find the diameter of this circle is

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 : )
