0=-20.5x+16.35x-0.1245

The value of x in the given equation is 0.03

Step-by-step explanation:

The given equation is that

The steps to be followed to solve the equation are :

Add the like terms together to reduce the equation in a simplified form.

Here, there are two x terms and they must be reduced to a single term.

For this, add the both terms together so that the equation is simplified into one x term and a constant term.

⇒

⇒

To eliminate the constant term on the left side of the equation, add 0.1245 on both sides.

⇒

⇒

Now, the equation is further simplified by dividing 4.15 on both sides,

⇒

⇒

Therefore, the value of x is 0.03

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
