Answer:

The capacity of the container is 2546.78 cm³.

Step-by-step explanation:

The volume of the frustum of a cone is:

\text{Volume}=\frac{\pi h}{3}\cdot[R^{2}+Rr+r^{2}]

The information provided is:

r = 16/2 = 8 cm

R = 24/2 = 12 cm

h = 8 cm

Compute the capacity of the container as follows:

\text{Volume}=\frac{\pi h}{3}\cdot[R^{2}+Rr+r^{2}]

            =\frac{\pi\cdot8}{3}\cdot[(12)^{2}+(12\cdot 8)+(8)^{2}]\\\\=\frac{8\pi}{3}\times [144+96+64]\\\\=\frac{8\pi}{3}\times304\\\\=2546.784445\\\\\approx 2546.78

Thus, the capacity of the container is 2546.78 cm³.

25/6-4x=-9x+5/6 Steps?
LenKa [72]

Answer:

<h2>X=1.33</h2>

solution,

\frac{25}{6}  - 4x =  \frac{ - 9x + 5}{6}  \\  \: or \:  \frac{25 - 4x \times 6}{6}   =  \frac{ - 9x + 5}{6}  \\ or \:  \frac{25 - 24x}{6}  =  \frac{ - 9x + 5}{6}  \\ or \: 6(25 - 24x) = 6( - 9x + 5) \\ or \: 150 - 144x =  - 54x + 30 \\ or \:  - 144x + 54x = 30 - 150 \\ or \:  - 90x =  - 120 \\ or \: x =  \frac{ - 120}{ - 90}  \\or \:  x =  \frac{4}{3}  \\ x = 1.33

Hope this helps.

What is the volume of the cylinder?
mamaluj [8]

Answer/Step-by-step explanation:

Volume of a cylinder is given as V = πr²h

Where,

radius (r) = 6 cm

height (h) = 8 cm

Plug in the values

V = π*6²*8

V = π*36*8

V = π*288

V = 288π cm³ or 904.78 cm³
