The rounded answer: 276,000
Answer:
V = 3078.76 in³
Step-by-step explanation:
To find the volume of a cylinder, use this formula:
V = πr²h
- V = volume
- r = radius
- h = height
Plug in the values you know.
V = π(7)²(20)
First let's evaluate the exponent.
7² = 49
V = π(49)(20)
Now let's multiply.
49 • π = 153.938
153.938 • 20 ≈ 3078.76
V = 3078.76 in³
This is your answer.
Hope this helps!
Slope is the change in y-values divided by the change in x-values. You can use the following formula to calculate slope:
y₁ - y₂ / x₁ - x₂
The coordinates: (1, 7) and (10, 1)
y₁ = 7
y₂ = 1
x₁ = 1
x₂ = 10
7 - 1 / 1 - 10
6 / -9
-2 / 3
Answer:
The slope of the line that passes through the points (1, 7) and (10, 1) is -2/3.
Since the dimensions of the length and width are equal, then the board and the picture are squares. The width of the board is the margin surrounding the picture. Let's denote the width to be x. The length of the picture plus the length of the width at both ends should equal the length of the board. So, the equation should be:
10 1/2 in = 8 3/4 + 2x
Solving for x
x = 7/8 inches
