9.4 is the distance coming back with pythagorean theorem
add the original 13 miles
22.4 miles
The total volume is the sum of volume of cone and volume of cylinder.
Volume of cylinder = πr²h
π = 3.14
r = 4/2 = 2 mm
h = 2 mm
So, volume of cylinder equals:

mm³
Volume of cone =

π = 3.14
r = 2 mm
h = 3 mm
So, volume of cylinder equals:

mm³
Thus, total volume of the figure = 25.12 + 18.84 = 43.96 mm³
The third one
c^5•d^5
Hope this helps!
The equation would be worded as: 2m+16=36.
Solve! Using the subtraction property of equality, 2m=20. Then the division property of equality lets us figure out that m=10.
