Answer:
Approximate area is 190cm^2
Call the radius r and the height of the cone h. The formula for the volume of a cone is r^2*h*pi/3, and the formula for the volume of a sphere is 4r^3/3, so half of a sphere has volume 2r^3/3. Adding these, our answer is:
Answer:
6x + 3
Step-by-step explanation:
Just add the X's (5x + x)=6x, since there is only one whole number without any variables you dont have to do anything to it. So 6x + 3 is your answer.
The answer is: "4" .

<u>Note</u>: The question asks for a whole number.
"The area of the triangle above will equal one half of a rectangle that is 5 units long and <u> 4 </u><u /> units wide. (Input only whole numbers, such as 8.).
______________________________________________________
<u>Note</u>: The diagram shows a "right triangle" ; which would be "one-half" of a rectangle, with units of "length" being "5 units" (as mentioned in this very question prompt; and a width of "4" units (as shown in the diagram; hence the answer is "4" units).
Furthermore, the formula/equation for the area, "A" , of a triangle is:
A = (1/2) * b * h ;
that is:
Area = (1/2) * (base length) * (perpendicular height).

As such, the answer, "4" (units) makes sense.
