Nine less than three times a number is greater than forty

pentagon [3]

Start with an equation.
Nine less... so -9
3 times a number = 3x
Greater than 40 is >40

So put together is 3x-9>40
When solving I imaging the greater than sign as an equal sign. Less confusing.
3x-9=40
3x=49
x>49/3

Orange traffic cones come in a variety of sizes. Approximate the volume, in cubic inches, of a traffic cone that has a height of

Irina18 [472]

Answer:

Volume of the cone = 628 cubic inches.

Step-by-step explanation:

Given:

Height of the traffic cone, $h$ = 2 feet = 24 inches ...[1 feet =12 inches]

Diameter of the cone, $d$ = 10 inches

Radius of the cone, $r$ = 5 inches ...[ $r=\frac{d}{2}$ ]

Value of pie, $\pi$ = 3.14

We have to find the approximate volume.

Lets say that the volume is $V$ .

Formula:

Volume of a cone = $\frac{\pi r^2h}{3}$

So,

⇒ $V=\frac{\pi r^2h}{3}$

⇒ Plugging the values.

⇒ $V=\frac{3.14\times 5^2\times 24}{3}$

⇒ $V=\frac{3.14\times 25\times 24}{3}$

⇒ $V=628$ $inches^3$

The volume of the orange traffic cone is 628 inches^3.
