Answer:
Volume of the prop = 706.5 in³
Step-by-step explanation:
Volume of the prop given in the picture = Volume of hemisphere + Volume of the cone
Volume of the hemisphere = ![\frac{2}{3}\pi r^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
where 'r' = radius of the hemisphere
For r = 5 in,
Volume of the hemisphere = ![\frac{2}{3}(3.14)(5)^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%283.14%29%285%29%5E%7B3%7D)
= 261.67 in³
Volume of a cone = ![\frac{1}{3}\pi r^{2}h](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E%7B2%7Dh)
Here r = radius of the circular base
h = height of the cone
For 'r' = 5 in and h 17 in.
Volume of the cone = ![\frac{1}{3}(3.14)(5)^2(17)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%283.14%29%285%29%5E2%2817%29)
= 444.83 in³
Volume of the prop = 261.67 + 444.83
= 706.5 in³
