It is 26635.2384 because you multiply the pi times the radius18.8 to the 2nd power times the height that is 24
The median of the numbers would be 7.5
The answer is 22 minutes:
20x for Tatsu and 10x for Andy
30x = 11
x = 11/30
11/30 * 60 = 22
This is a trapezoid and the trapezoid formula is b1 plus b2/ 2 times height.
17 plus 5 is 22. Divided by 2 is 11.
Now, we have to multiply 11 by the height : 5.
11 times 5 is 55 and that is your area. 55 units squared.
30+5=5+30 with commutative property or 30+5=35
