1. A circle has a diameter of 7.6 feet. Which measurement is closest to the circumference of this circle? Use 3.14 to approximate π.

a. 23.9 ft
b. 45.3 ft
c. 47.7 ft
d. 11.9 ft

a. 23.9 ft

Step-by-step explanation:

The circunference of a circle is given by the following formula:

In which r is the radius.

A circle has a diameter of 7.6 feet.

The radius is half the diameter. So

The circunference is

So the correct answer is:

a. 23.9 ft

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

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 : )
