I’m so sorry! I hope you find the answer soon! I’m stressing out as well
We have a rectangle with length L that is 3 inches more than the width W. Then we can write this as:
The area of the rectangle is 180 square inches.
We have to find the width W.
As the area is equal to the product of the length and the width, we can write this equation and solve for W as:
We have a quadratic equation. The roots of this equation will be the mathematical solutions.
We can find the roots using the quadratic formula:
The solutions are W = -15 and W = 12.
The first one is not valid, as W has to be greater than 0.
Then, the solution to our problem is W = 12 in.
Answer: the width is W = 12 inches.
Answer:
Step-by-step explanation:
Volume of a right circular cone can be found using the equation
where
- r is the radius of the cone
- h is the height of the cone
- pi is the π constant
Since r=4ft, we can model the volume of the water in the cone in terms of the height as
=
First you want to find the area of the square, which would be 121. ( 11 x 11 )
Next you want to find the area of the circle, 78.54 ((pi)5^2)
Last, you want to subtract the area of the circle, from the area of the square that is shaded. Youre left with 42.46
Hope this helped
