Given:
Trapezoid with bases 10 and 20, and height of the trapezoid is 6.
To find:
The area of the trapezoid.
Solution:
We know that the area of a trapezoid is:

Where, h is the height of the trapezoid and
are bases of the trapezoid.
Putting
in the above formula, we get



The area of the trapezoid is 90 sq units. Therefore, the correct option is A.
Answer: SECOND OPTION (52 cm³)
Step-by-step explanation:
The formula for calculate the volume of a cone is:

Where r is the radius and h is the height.
The formula for calculate the volume of a cylinder is:

Where r is the radius and h is the height.
As you can see, the difference between the the formulas is that r²hπ of the cone is divided by 3. Therefore, if you know the volume of the cylinder and you know that the cone has the same base and height as the cylinder, you have to divide the volume of the cylinder by 3 to obtain the volume of the cone.
Therefore, the result is:

<span>Solutions or Roots of Quadratic Equations. A real number x will be called a solution or a root if it satisfies the equation, meaning . It is easy to see that the roots
are exactly the x-intercepts of the quadratic function , that is the
intersection between the graph of the quadratic function with the
x-axis.</span>
Step-by-step explanation:
The longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.
So the smallest angle is <P.
