The answer is 113.04. Volume of a sphere is 4/3*pi*r³so 4/3*3.14*3³=113.04
Answer:
It can be decomposed into the following simplest shapes:
Two Rectangles and one Triangle.
The area is 
Step-by-step explanation:
You can observe in the picture attached that it can be decomposed into the following simplest shapes:
Two Rectangles.
One Triangle.
The area of the a rectangle can be found with:
Where "l" is the length and "w" is the width.
You can identify in the picture that:
Substituing values, you get that the areas of the rectangles A and B are:
The formula for the area of a triangle is:
Where "b" is the base and "h" is the height.
In this case:
Then, its area is:
Then, the total area of carpet that Valerie needs for her project is:
A jar of marbles = 4/4 or 12/12
He gave kayla 3/4 or 9/12 he left 1/4 or 3/12 in the jar
Kayla returned 1/3 or 4/12
3/12+ 4/12 = 7/12
7/12 of the jar is full
