In a circle graph, what percent would be represented by a 25° angle? (round to nearest whole number if needed) A. 7%
B. 6%
C. 9%
D. 8%

A) 7%

Step-by-step explanation:

There are 360 degrees in a circle.  Thus, a 25 degree sector would make up 25/360 of the circle.  25/360 can be simplified to .06944444.  This rounds to .07, which is 7%.

A. 7%

Step-by-step explanation:

A percent can be found by dividing the part by the whole and multiplying by 100.

(part/whole) *100

There are a total of 360 degrees in a circle. This is the whole.

We want to find what percent a 25 degree angle will take up. This is the part.

(25/360) * 100

First, divide 25 by 360.

0.0694444444 * 100

Now, multiply the numbers together  

6.94444444 %

Round to the nearest whole number. The 9 in the tenth place tells us to round the 6 to a 7.

7 %

Therefore, the answer is A. 7%

a. is correct
