Sin = surd 3 / 2
get it????
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
-8, -19, -30, -49 , -60
<u>Step-by-step explanation:</u>
Here we have the following sequence :
-8, -19, -30, _ , _
- First term of sequence is -8 .
- Second term of sequence is -19 :
- Third term of sequence is -30 :
- Fourth term of sequence is :
- Fifth term of sequence is :
Following sequence was an AP( Arithmetic Progression ) with first term as -8 i.e. 
and common difference 
having general equation as : 
.
Answer:
Henri filled 18 gift bags. Hope this helps!!
Step-by-step explanation:
You half to divide how many candies that you are putting in the bag by the amount you have. So if you have 432 candies and you are putting 24 in each bag you would have 18 bags.
19ft Estimate the length of one side of a square floor,if the area is 320 square feet.give the whole number that is closest to the amount. the square root of 320 is 17.88,rounded is 18.
