Step-by-step explanation:
To find the area of this section of the triangle, we will have to find the area of the sector, and then subtract the area of the triangle. To first find the area of the sector of the circle. Remember that the sector of a circle can be found using a proportion of angles. Since there is an angle of 90 degrees in the center. We will take that and divide it by 360 degrees, which is an entire circle. , so the sector is one-quarter of the entire circle. Now find the area of the entire circle which will be
×
, where r is 6 since it is the radius of the circle. So therefore the area of the sectore will be a quarter of 36
, which is 9
.
Now you must find the area of the triangle with side length 6. Remember, this is an isosceles triangle with sides length of 6 because two of the sides are radii. Also, remember that this is a 90 degree triangle, so the area of the triangle is simply , which is 18 cm^2.
Now to find the area of just the yellow segment, just take the area of the sector we found, and subtract the area of the triangle. Therefore, the answer is
Hope this helped.
Question is Incomplete; Complete Question is given below;
For a fundraiser, Hailey raises $27, plus 1.50 for each lap she swims. Tariana raises $18, plus $3 for each lap she swims what is the total amount raised by each swimmer after swimming laps. after how many laps would the two swimmers have raised the same amount of money?
Answer:
If they swim 6 laps they would raise same amount of money.
The Total amount of money they raised is $36 after 6 laps.
Step-by-step explanation:
Let number of laps swim by the swimmers be x
Given:
Hailey raises $27, plus 1.50 for each lap she swims.
Hence It means amount raised by Hailey is the sum of $27 and 1.50 multiplied by Number of laps she swim.
Framing in equation form we get;
Amount of Money raised by Hailey =
Also Given:
Tariana raises $18, plus 3 for each lap she swims.
Hence It means amount raised by Tariana is the sum of $18 and 3 multiplied by Number of laps she swim.
Framing in equation form we get;
Amount of Money raised by Tariana =
Hence The expression representing the Total amount raised by Hailey is and by Tariana is
,
Now We need to find the Number of laps they swim so as the would raise the same amount of Money;
Hence equation can be framed as;
Combining common terms we get;
Hence If they swim 6 laps they would raise same amount of money.
Now we will find the amount they both will raise by substituting the value of x we get;
Amount of Money raised by Hailey =
Amount of Money raised by Tariana =
Hence The Total amount of money they raised is $36 after 6 laps.
