Answer:
Volume of Cylinder using Cavalieri's Principle is
.
Step-by-step explanation:
Given that,
Area of cross-section of a solid cylinder is
.
Height of solid is
.
According to Question,
The Cavalieri's Principle : if two or more solid figures have same cross-sectional area at energy level and height is same then its volume is same.
So, Volume of Cylinder = ![Area \ of \ cross-section \times height](https://tex.z-dn.net/?f=Area%20%5C%20of%20%5C%20cross-section%20%5Ctimes%20height)
Substituting the given value we get,
Volume of cylinder = ![803.84ft^{2} \times 12.25ft](https://tex.z-dn.net/?f=803.84ft%5E%7B2%7D%20%5Ctimes%2012.25ft)
![= 9847.04 ft^{3}](https://tex.z-dn.net/?f=%3D%209847.04%20ft%5E%7B3%7D)
Hence, Volume of Cylinder using Cavalieri's Principle is
.
Answer:
Step-by-step explanation:
The angle of 2 is 75 degrees.
Angle 1 = 180 - 75 = 105 degrees
If the two lengths are 7 and 3, then I believe the length of the hypotenuse would be approximately 7.62.
Answer:
PE = 83 and Science = 71
Step-by-step explanation:
let P represent PE and S represent Science with P > S, then
P + S = 154 → (1)
P - S = 12 → (2)
Adding the 2 equations term by term eliminates S
2P = 166 ( divide both sides by 2 )
P = 83
Substitute P = 83 into (1)
83 + S = 154 ( subtract 83 from both sides )
S = 71
Hence PE mark = 83 and Science mark = 71
