Area of flask: 63.62
Diameter: 4.5
Radius: 4.5 divided by 2
Radius: 2.25
Pi: 3.14
Volume:
1- 4/3(PI)(radius) by cubic square
2- 4/3(3.14)*(2.25) by cubic square
Answer: 47.71
Area of tank:
7-2=5
(it tells u to leave 2cm of the height without water)
15(L) x 9(W) x 5(D) = 675
675-47.71= 627.69
1 Liter= 1000 Cm
627.69 Cm = 0.62769 Liters
( round to nearest 0.1 liter )
Answer: 0.6 liters
A
Answer: d
Step-by-step explanation: trust me ok
That's a question about the Pythagorean Theorem.
We use the Pythagorean Theorem to find the value of one side in a right triangle.
This theorem says that:
![\boxed{a^2 = b^2 + c^2}](https://tex.z-dn.net/?f=%5Cboxed%7Ba%5E2%20%3D%20b%5E2%20%2B%20c%5E2%7D)
- <em>a</em> is the hypotenuse (It's the opposite side the right angle).
- <em>b</em> and <em>c </em>are cathetus (They're the adjacent sides the right angle).
Okay, now, let's go to solve this problem! In our figure, we have two cathetus. Their values are 10 and 7 and we have to find the value of <em>x </em>(the hypotenuse). Let's change this information in that formula.
![a^2 = b^2 + c^2\\x^2 = 10^2 + 7^2\\x^2 = 100 + 49\\x^2 = 149\\x = \sqrt{149}](https://tex.z-dn.net/?f=a%5E2%20%3D%20b%5E2%20%2B%20c%5E2%5C%5Cx%5E2%20%3D%2010%5E2%20%2B%207%5E2%5C%5Cx%5E2%20%3D%20100%20%2B%2049%5C%5Cx%5E2%20%3D%20149%5C%5Cx%20%3D%20%5Csqrt%7B149%7D)
Therefore, the value of <em>x </em>is
.
I hope I've helped. :D
