Answer:
Last option: 
Step-by-step explanation:
If the shell of a bass drum was cut down one side and laid flat, the resulting shape would be a rectangle.
The area of a rectangle can be calculated with the formula:
Where l is the lenght and w is the width.
In this case, the lenght of the rectangle obtained (the lenght of the shell) is the circumference of the drum.
Remember that the circumference of the circle can be calculated with:
Where r is the radius of the circle.
Then:
The width is the height of the shell:
Then, substituting into , you get:
Answer:
Step-by-step explanation:
An imaginary number is the square root of a negative real number. So the square root of positive 12 would be the same thing but without the ( <em>i</em> ).
Answer:
Each of the other side is 184 feet.
Step-by-step explanation:
Given that:
Length of two sides each = 104 feet
Total length of all sides = 576 feet
Let,
x be the length of other one side.
Length of other two sides will be 2x.
Total length of sides = 2x + 2(104)
576 = 2x + 208
2x = 576 -208
2x = 368
Dividing both sides by 2
Hence,
Each of the other side is 184 feet.
Answer:
B. (5,-2)
Step-by-step explanation:
Plug in X and Y, verify accuracy
The base is 15 ft.
Using the formula A=bh, we substitute the information we have. We know the area and the height:
127.5 = b(8.5)
Divide both sides by 8.5:
127.5/8.5 = b(8.5)/8.5
15 = b
The base is 15.
