pls help me to solve this question with proper solution....​

Answer 1

Answer:

$option \: d \: is \: correct \: answer$

Step-by-step explanation:

The volume of the grain silo can be found by adding the volumes of all the solids of which it is composed.

The silo is made up of a cylinder with height 10 feet and base radius 5 feet and two cones, each having height 5 feet and base radius 5 feet.

The formulas volume of cylinder

$\pi {r}^{2}h$

and volume of cone

$\frac{1}{3}\pi {r}^{2}$

can be used to determine the total volume of the silo.

Since the two cones have identical dimensions, the total volume, in cubic feet, of the silo is given by:

$v = \pi( {5}^{2} )(10) + 2 \frac{1}{3} \pi( {5}^{2} )(5) \\ = > \frac{4}{3}(250)\pi \\ = = > 1047.2 \: cubic \: feet$

Answer 2

Step-by-step explanation:

Aloha !

v= πr²h+⅓πr²

v=π(5)²10+⅓π(5)²

v=π.25.10+⅓π.25

v=4/3{260}π

v=1047.2 cubic metres
