Answer:

1112 m^{3}

Step-by-step explanation:

The formula for the surface area of a conical grain storage is:

S= \pi *r\sqrt{r^{2}+ h^{2} } +\pi *r^{2}

Now you just have to put the values inside the formula, knowin that the radius is half the diameter the radius would be:

\frac{d}{2}=\frac{14}{2}=7

ANd the height is 43.

So the formula would be:

S= \pi *7\sqrt{7^{2}+ 43^{2} } +\pi *7^{2}

S=1112m^{3}

I want to know how to solve multi step equation
Anastasy [175]

We are given:

4x+10=7x+16

Our goal in solving for any variable, in this case is x, we need to isolate x on one side of the variable. Let's start by subtracting 7x from both sides, which will cancel the +7x on the right side. We are then left with:

-3x+10=16

Now, we want to move that +10 to the other side so our x is all by itself. Let's subtract 10 from both sides, which will cancel the +10 on the right leaving us with:

-3x=6

Since we cannot have a coefficient when solving for x, we need to divide both sides by -3.

\frac{-3x}{-3}={\frac{6}{-3}

When we divide, our answer is:

x=-2
