Think of the two pieces together as a single cone of height 19, and its volume.
Then think of only the upper piece as a cone, and find its volume.
The volume of the frustum is the total volume minus the volume of the upper piece.
The volume of a cone is:
Total volume:
Volume of upper cone:
Volume of frustum:
it is infintely many i think so
Check the picture below.
you really have two rectangles, a 6x10 and a 6x5, and surely you know what those areas are, so sum them up, and that's the area of the polygon.
7.) (x, y) —> (1/2*x, 1/2*y)
Answer:
Step-by-step explanation:
The formula for area of a triangle is
Now we have to isolate for w.
First multiply by the 2 which is the reciprocal of 1/2 to cancel it out.
Now divide by h to isolate w.
