Question

What is the surface area of a conical grain storage tank that has a height of 43 meters and a diameter of 14 meters? Round the answer to the nearest square meter

Answer 1

check the picture below

Answer 2

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=1112$m^{3}$
