Assuming the shape is a piece of a circle, you can determine the ratio of the shape to a full circle. A full circle will have 360 degree but this shape is only 40 degree. Then the ratio would be: 40/360= 1/9 full circle.

Then, using the circle area formula, the area of the 1/9 circle would be:
full circle area= pi * r^2
full circle area= 22/7 * 6^2
full circle area= 792/7
1/9 full circle area= 792/7*9= 88/7 = 12.57

What percent of 50 is 15

juin [17]

To find the percent, first divide the part by the whole.

$\frac{Part}{Whole} = \frac{15}{50}$

Now divide:

$15 \div 50 = 0.3$

You have your answer as a decimal. To change your decimal into a percent, move the decimal point 2 places to the right and add a percent sign.

First move the decimal point:

$0.3 \rightarrow 30$

Now add the percent sign:

$30 \rightarrow 30 \%$

30% of 50 is 15
