Answer:
8 half cubes
Step-by-step explanation:
8 half cubes
we know that
surface area of the cylinder=2*{area of the base}+perimeter of base*height
area of the base=pi*r²
r=40 ft
Area of base=pi*40²
Area of the base=1600*pi ft²
Perimeter of the base=2*pi*r
Perimeter of the base=2*pi*40
Perimeter of the base=80*pi ft
surface area of the cylinder=2*1600*pi+80*pi*17
surface area=4560*pi ft²
therefore
the answer is the option
4560π ft2
Answer:
12
Step-by-step explanation:
3 times 4 is 12
Answer: 8.55 miles
Step-by-step explanation:
Adding the totals given in the problem together:
1.8 miles + 6.75 miles = 8.55 miles.
Therefore, because we descended the plane and are looking for the previous height, we just add the descent to the elevation AFTER descent.
