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

Area = 44 ft2<br> (x – 12) ft<br> (x - 5) ft
Maru [420]

Answer:

x = 16 feet

Step-by-step explanation:

I'm guessing the shape given is a rectangle? Anyways, to find the area we multiply the sides, this gives us the equation:

(x - 12)(x - 5) = 44

We can distribute to get

x^2 - 12x - 5x + 60 = 44

x^2 - 17x + 60 = 44

Now, to get the equation equal to zero, we can subtract 44 from both sides:

x^2 - 17x + 16 = 0

To factor this, we are looking for two numbers that multiply to 16 and add up to -17. These two numbers are -1 & -16, therefore, the factored form is:

(x - 1)(x - 16) = 0

We can use the zero product property to say x = 1 and x = 16. We can cross out the solution x = 1, because when plugged in, we get side lengths less than one. So the sole answer is x = 16.
