Step-by-step explanation:
Part A.
We are given the total volume of the amount of sand she will want to fill
we are also given the shape and dimensions of the cylinders
Total volume of the sand = 1,000
Cylinder= radius 4 in, and height 8 in
the volume of a cylinder is V=πr^2h
We will solve for the volume of the cylinders
V=πr^2hV=π(4)^2*(10)
V = π (16) * (10)
V = π 160
The volume of the cylinders she wants to fill is 502.65 in^3
How many cylinders will she need
Well,
1000/502.65 <span>≈ 1.98
She will need two cylinder cans to fill with the 1,000 in^3 of sand
Part B.
To see if this is true, we find the half of the original cylinder's radius and height then solve for the volume and compare
</span>V=πr^2h
<span>The height and radius of the original cylinders were 4 r and 8h
we will find half of that which will be : 2 r and 4 h
Now solve for the volume </span>V=πr^2h
V=π(2)^2* (4)
V=π (4)*(4)
V = π 16
V ≈<span> 50.26 inches ^3
The volume of the original cylinders was </span>502.65 in^3 and the volume of the new cylinders is 50.26 in^3... Clearly the volume of the new cylinders is NOT half of the original. Sally is not correct!

Answer:


Step-by-step explanation:
<u>Second-Degree Equation</u>
The second-degree equation or quadratic equation has the general form

where a is non-zero.
There are many methods to solve the equation, one of the most-used is by using the solver formula:

The equation of the question has the values: a=1, b=2, c=4, thus the values of x are


Since the square root has a negative argument, both solutions for x are imaginary or complex. Simplifying the radical

The solutions are


D
Step-by-step explanation:
2/6 is litterally right there cause it has seven lines and tge 0 doesnt count
<u>Given:</u>
Each circle has a diameter of 2 inches each.
The outer square has a side length of 4 inches and the square ABCD has a side length of 2 inches.
<u>To find:</u>
The area of the shaded region.
<u>Solution:</u>
Each circle has a diameter of 2 inches. The square ABCD is at the center of each circle so it has a side length of 1 inch.
To determine the area of the shaded region, we subtract the area of the quarter-circles in the square ABCD from the area of the square ABCD.
The area of a quarter-circle 
All the quarter-circles have a radius of 1 inch.
The area of 1 quarter-circle 
The area of 4 quarter-circles 
So the area of the quarter-circles in the square ABCD is 3.1514 square inches.
The area of a square 
The area of square ABCD 
The area of the shaded region 
The area of the shaded region is 0.8585 square inches.
