Answer:
<u>27</u> students are girls.
Step-by-step explanation:
Given:
There are 3/4 as many girls as there are boys.
In the fifth grade total there are 63 students.
Now, to find the number of students that are girls.
Let the number of students that are boys be
So, the number of students that are girls =
Total number of students = 63.
Now, to get the number of students that are girls we solve an equation:
Now, substituting the value of :
Therefore, 27 students are girls.
The surface area of the figure given is of: 61.3 yd².
<h3>What is the combined surface area of a figure?</h3>The combined surface area of a figure is the area of each figure.
This figure is composed by:
- A circle of radius 3 yd.
- A triangle with base 6 yd and one leg 11.4 yd.
The area of the circle is given as follows:
For the triangle, we need to find it's height, which is the <u>leg of a right triangle, in which one of the sides is 3 and the hypotenuse is 11.4</u>, hence:
h² + 3² = 11.4²
h = 11 yd.
Hence the area of the triangle is:
A = 0.5 x 6 x 11 = 33 yd²
The surface area of the figure is:
9pi + 33 yd² = 61.3 yd².
