<u>Given:</u>
A composite figure consisting of a cylinder with radius r and height h and a half-sphere with a radius r.
<u>To find:</u>
The total volume of the composite figure.
<u>Solution:</u>
To determine the total volume of the figure, we add the volume of the cylinder and the volume of the half-sphere.
The volume of a cylinder, ![V= \pi r^{2} h.](https://tex.z-dn.net/?f=V%3D%20%5Cpi%20r%5E%7B2%7D%20h.)
The given cylinder has a radius of 3.9 units and a height of 4.3 units. Assume π equals 3.14.
The volume of the cylinder,
cubic units.
The volume of a half-sphere, ![V= \frac{2}{3} \pi r^{3} .](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B2%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D%20.)
The given half-sphere has a radius of 3.9 units, assume π equals 3.14.
The volume of the half-sphere,
cubic units.
The total volume of the composite figure
cubic units.
Rounding this off to the nearest hundredth, we get the volume of the cone as 329.54 cubic units.
Answer:
44.77

Answer:
at x =
,
= -3.5
Step-by-step explanation:
The given equation is ![-3x^{2} + \sqrt{2}x + \frac{1}{2}](https://tex.z-dn.net/?f=-3x%5E%7B2%7D%20%2B%20%5Csqrt%7B2%7Dx%20%2B%20%5Cfrac%7B1%7D%7B2%7D)
Now, substitute the value of x =
in the above equation.
The given equation simplifies to,
![-3(\sqrt{2})^{2} + (\sqrt{2})(\sqrt{2}) + \frac{1}{2}](https://tex.z-dn.net/?f=-3%28%5Csqrt%7B2%7D%29%5E%7B2%7D%20%2B%20%28%5Csqrt%7B2%7D%29%28%5Csqrt%7B2%7D%29%20%2B%20%5Cfrac%7B1%7D%7B2%7D)
now, ![\sqrt{2} . \sqrt{2} = 2, \textrm{and} (\sqrt{2} )^{2} = 2](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D%20.%20%5Csqrt%7B2%7D%20%20%3D%202%2C%20%5Ctextrm%7Band%7D%20%28%5Csqrt%7B2%7D%20%29%5E%7B2%7D%20%3D%202)
So, the equation become
-3(2) + 2 + (1/2) =
= -3.5
So, at x =
,
= -3.5
