Answer:
The answer is 5/13
Step-by-step explanation:
I don't have a explanation but I do know this answer is correct because i has this question on my test.
Answer:
volume of the figure after rotation=56.52 cubic units.
Step-by-step explanation:
<em>After rotating the figure around the line y=x, we will see that the coordinates (x,y) change to the coordinates (y,x).</em>
Hence the coordinates of the triangle (0,0),(6,6) and (9,3) changes to (0,0),(6,6) and (3,9).
we will get a cone on rotating the triangle across y=x.
The radius of cone(r)=3 units.
height of cone(h)=6 units.
volume of the cone= 
.
Hence, volume of cone= 56.52 cubic units.
Answer:
84? Not sure but pretty sure
Step-by-step explanation:
In a straight line, the word can only be spelled on the diagonals, and there are only two diagonals in each direction that have 2 O's.
If 90° and reflex turns are allowed, then the number substantially increases.
Corner R: can only go to the adjacent diagonal O, and from there to one other O, then to any of the 3 M's, for a total of 3 paths.
2nd R from the left: can go to either of two O's, one of which is the same corner O as above. So it has the same 3 paths. The center O can go to any of 4 Os that are adjacent to an M, for a total of 10 more paths. That's 13 paths from the 2nd R.
Middle R can go the three O's on the adjacent row, so can access the three paths available from each corner O along with the 10 paths available from the center O, for a total of 16 paths.
Then paths accessible from the top row of R's are 3 +10 +16 +10 +3 = 42 paths. There are two such rows of R's so a total of 84 paths.
