Ateam of engineers must design a fuel tank in the shape of a cone (excluding the base) is given by the formula s=pi x square root of (r^2 + h^2). find the radius of a cone with a height of 21 meters and a surface area of 155 meters squared. round your answer to the nearest tenth if necessary.

The radius of cone is 44.6 meters.

Step-by-step explanation:

Consider the provided information.

The shape of a cone (excluding the base) is given by the formula S=Pi x square root of (r^2 + h^2).

This can be written as:

We need to find the radius of a cone with a height of 21 meters and a surface area of 155 meters squared.

Substitute the respective values in the above formula.

Hence, the radius of cone is 44.6 meters.

is only a line? i think so

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
