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

1112
`m^(3)`

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:

`(d)/(2)=(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)`
