Answer:
396 
Step-by-step explanation:
Okay, so first we will find the triangle area.
9 * 8 = 72/2 = 36.
Now multiply this by 11 (the width of the prism)
36 * 11 = 396 
This statement is true, or else you wouldn't have a sphere.
If this question is as simple as it seems all you would have to do is subtract. If he is down 96 feet then goes up 49 feet you would do 96-49.
The answer is 47 feet.
I hope this helps! Let me know if this is right.
Okay so because it's 10% off you're going to take the original price ($25) and move the decimal over once. So, $2.50. Now back to the original price!
$25.00 - $2.50 = $23.50 for the sweatshirt. I don't think I explained that very well, but that'd be how you found your answer?
