Answer:
B
Step-by-step explanation:
The formula for the volume of a cylinder is
, where r is the radius of the base and h is the height of the cylinder.
![\pi \cdot 3.25^2 \cdot 10=105.625\pi \text{ cm}^3](https://tex.z-dn.net/?f=%5Cpi%20%5Ccdot%203.25%5E2%20%5Ccdot%2010%3D105.625%5Cpi%20%5Ctext%7B%20cm%7D%5E3)
Therefore, the correct answer is choice B. Hope this helps!
Answer:
![V_s=85\ cm^3](https://tex.z-dn.net/?f=V_s%3D85%5C%20cm%5E3)
Step-by-step explanation:
Let
be the volumes of the smaller and bigger cylinder.
The formula for the volume of a cylinder is given by :
![V=\pi r^2 h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2%20h)
As the two triangles are similar, the cube of their ratio would equal the ratio of their volume i.e.
![\dfrac{V_s}{V_b}=(\dfrac{h_s}{h_b})^3\\\\\dfrac{V_s}{V_b}=(\dfrac{3}{5})^3\\\\\dfrac{V_s}{V_b}=0.216\\\\V_s=393\times 0.216\\\\V_s=84.8\\\\or\\\\V=85\ cm^3](https://tex.z-dn.net/?f=%5Cdfrac%7BV_s%7D%7BV_b%7D%3D%28%5Cdfrac%7Bh_s%7D%7Bh_b%7D%29%5E3%5C%5C%5C%5C%5Cdfrac%7BV_s%7D%7BV_b%7D%3D%28%5Cdfrac%7B3%7D%7B5%7D%29%5E3%5C%5C%5C%5C%5Cdfrac%7BV_s%7D%7BV_b%7D%3D0.216%5C%5C%5C%5CV_s%3D393%5Ctimes%200.216%5C%5C%5C%5CV_s%3D84.8%5C%5C%5C%5Cor%5C%5C%5C%5CV%3D85%5C%20cm%5E3)
So, the volume of the smaller cylinder is equal to
.
