Question

Which point on the number line represents the approximate volume of a cone with a radius of 3 units and a height of 4 units? Use 3.14 for π.

Answer 1

Answer:

The point closest to the number 40

Step-by-step explanation:

To find volume of cone:

$V=\pi r^{2} \frac{h}{3}$

(but in this case we will be substituting $\pi$ for it approximation: 3.14)

So our new equation is $V= 3.14r^{2} \frac{h}{3}$

All right, let's get to work now.

• Following the order of operations our first step would be: $3^{2}$ or 3x3 wich is 9
• Next step would be 3.14x9, which is 28.26
• After that we would solve $\frac{4}{3}$, which is 1.3 repeating but we can round to the nearest tenth and get 1.3
• Next we would multiply 28.26 by 1.3 which is 36.73800

We would next round to the nearest whole and our final answer is: 37
