Answer:

The volume of the solid is $1,021m^3$

Step-by-step explanation:

1. Cylinder

For find the volume of a cylinder we use the next formula:

$V_{cylinder} = \pi h r^2 = \pi \cdot 9m\cdot (5m)^2 \approx 706.86m^3$

Then the volume of the cylinder is equal to $706.86m^3$

2. Cones

For find the volume of a cone we use the next formula:

$V_{cone} = \pi \frac{h}{3} r^2 = \pi \cdot \frac{6m}{3} \cdot (5m)^2 \approx 157.08m^3$

However there are two cones so we have to multiply the volume of one cone for two and we get the total volume for the cones which is $314.16m^3$

3. Sum of the volumes

Finally we sum the volumes of the cylinder and the cones for get the final result

$V_{cylinder} + V_{cones} = 706.86m^3 + 314.16m^3 \approx 1021m^3$

So approximating the result is $1021m^3$
