Answer:
1. 678.6
2. 1131
3. 490.1
4. 1809.6
Step-by-step explanation:
A=2πrh+2πr2
Answer:
1. SA = 216π cm² ≈ 678.24cm²
2. SA = 360π ft²≈ 1130.40ft²
3. SA = 156π yd² ≈ 489.84yd²
4. SA = 576π m² ≈ 1808.64 m²
Step-by-step explanation:
SA of a cylinder = 2πrh + 2πr²
1. r = diameter ÷ 2
r = 12/2 = 6
SA = 2π(6)(12) + 2π(6)²
SA = 144π + 72π
SA = 216π ≈ 678.24
2. r = 19/2 = 9
SA = 2π(9)(11) + 2π(9)²
SA = 198π + 162π
SA = 360π ≈ 1130.40
3. SA = 2π(6)(7) + 2π(6)²
SA = 84π + 72π
SA = 156π ≈ 489.84
4. r = 24/2 = 12
SA = 2π(12)(12) + 2π(12)²
SA = 288π + 288π
SA = 576π ≈ 1808.64

how do you find the diagonal of a rectangle prism please step by step
Answer: How to find diagonal length of a rectangular prism?
Step-by-step explanation:To find the diagonal distance of a prism, you can use the formula: \displaystyle d = \sqrt{w^{2} + l^{2} + h^{2}}, where = height; = width, and = length. \displaystyle d = \sqrt{2^{2} + 8^{2} + 10^{2} } = \sqrt{4 + 64 + 100} = \sqrt{168} = \sqrt{4 * 42} = 2\sqrt{42}.

Answer:
The graph below
Step-by-step explanation:
We have a graph and an equation and are asked to create the graph.
We need to keep in mind that y = 1/4x - 2 is a positive linear equation, since 1/4 though is a fraction, is still positive, along with that there is no exponent within the equation at all. So what we can know with this information, is that the line will be straight and ascending from negative to positive.
Step-by-step explanation:
You can draw it easily by compensating eBay values for X and finding Y value and then fold this equivalent in the sense of mode X at 0.1.2.3, and so and then find the value of Y and will be in this form

Can anyone please help me with this? You need to find the equation to solve for x, the value of x, and the value of each angle measure for all 5 questions. I will give brainliest
Answer:
1. a) 3x + 21 = 6x - 60
b) x = 27
c) angle measure = 102º
2. a) 12x - 18 = 8x + 10
b) x = 7
c) angle measure = 66º
3. a) 7x + 9 + 5x + 3 = 180 (simplified: 12x + 12 = 180)
b) x = 14
c) 107º; 73º
4. a) 3x + 10 + 3x -28 = 180 (simplified: 6x -18 = 180)
b) x = 33
c) 109º; 71º
5. a) 12x + 15 = 15x
b) x = 5
c) 75º
Step-by-step explanation:
1. a) they're the same angle so set them equal to each other: 3x + 21 = 6x - 60
b) solve from the equation above
3x + 21 = 6x - 60 subtract 3x from both sides
21 = 3x - 60 add 60 to both sides
81 = 3x divide both sides by 3
x = 27
c) plug back into each equation (they should be the same, but do both just to check)
3(27) + 21 = 81 +21 = 102º
6(27) - 60 = 162 - 60 = 102º
2. a) again, they're the same angle measure so set them equal to each other: 12x - 18 = 8x + 10
b) solve the equation for x
12x - 18 = 8x + 10 subtract 8x from both sides
4x - 18 = 10 add 18 from both sides
4x = 28 divide both sides by 4
x = 7
c) plug back into each equation (they should be the same, but do both just to check)
12(7) - 18 = 84 - 18 = 66º
8(7) + 10 = 56 + 10 = 66º
3. a) the sum of the two angles is 180º so 7x + 9 + 5x + 3 = 180
if you want the equation simplified: 12x +12 = 180
b) solve for x, i will be using the simplified equation
12x + 12 = 180 subtract 12 from both sides
12x = 168 divide both sides by 12
x = 14
c) plug into each equation to get the two angle measures
7(14) + 9 = 98 + 9 = 107º
5(14) + 3 = 70 + 3 = 73º
4. a) the sum of the two angles is 180º so 3x + 10 + 3x -28 = 180
if you want it simplified: 6x -18 = 180
b) solve for x, i will be using the simplified equation
6x - 18 = 180 add 18 to both sides
6x = 198 divide both sides by 6
x = 33
c) plug into each equation to get the two angle measures
3(33) + 10 = 99 + 10 = 109º
3(33) - 28 = 99 - 28 = 71º
5. a) they're the same angle measure so set them equal to each other: 12x + 15 = 15x
b) solve for x with the equation above
12x + 15 = 15x subtract 12x from both sides
15 = 3x divide both sides by 3
x = 5
c) plug back into each equation (they should be the same, but do both just to check)
12(5) + 15 = 60 + 15 = 75º
15(5) = 75º
