<h3>Answer:</h3>
301.6 cubic meters
<h3>Step-by-step explanation:</h3>
A cylinder is a shape with straight sides with circular or oval cross-sections. We know that the cylinder in the question must be a circular cylinder due to its radius description.
Volume Formula
A circular cylinder has a volume of
. In this equation, V is the volume, r is the radius, and h is the height. The question tells us that r=4m and h=6m. So, we can plug these values into the formula.
Solving for Volume
To solve plug the values into the formula and rewrite the equation.
Next, apply the exponents.
Then, multiply the constants.
Finally, multiply the remaining terms. Remember to use the pi button on the calculator and not an estimation to get a more exact value.
Make sure your answer is rounded to the correct digit. This means that the volume must be 301.6 cubic meters.
Answer:
5 feet.

Let x be the length of ramp.
We have been given that a ramp extends from the back of a truck bed to the ground. The back of the truck bed is 4 feet above the ground. The horizontal distance from the spot below the back of the truck bed to the bottom of the ramp is 3 feet.
We can see from our attachment that ramp and the height of truck bed form a right triangle, so the length of ramp will be equal to hypotenuse of right triangle with two legs of 4 feet and 3 feet.
We will use Pythagorean theorem to solve for the length of ramp.
![x^2=4^2+3^2](https://tex.z-dn.net/?f=x%5E2%3D4%5E2%2B3%5E2)
![x^2=16+9](https://tex.z-dn.net/?f=x%5E2%3D16%2B9)
![x^2=25](https://tex.z-dn.net/?f=x%5E2%3D25)
Upon taking square root of both sides of our equation we will get,
![x=\pm 5](https://tex.z-dn.net/?f=x%3D%5Cpm%205)
Since length of ramp can not be negative, therefore, length of ramp will be 5 feet.
True? are you asking for a true or false answer? be more specific please.
Circumference of a circle = 2 x pi x radius.
To find DE = 2 x pi x 15 = 94.25 cm. Then you divide 94.25 by 4 = 23.56 which round to one decimal point is 23.6 cm
