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:
y = -2x - 5
Step-by-step explanation:
y = -2x + b
- To find the y-intercept, plug the values of the variables.
5 = -2(-5) + b
5 = 10 + b
- Subtract 10 from both sides.
-5 = b
Divide them both by 6
So it should be : 3/4
Answer:
i will say 15 and -7
Step-by-step explanation:
15+-7=8 and 15--7=22
15+-7 so take the negative and take out that mush of the big number
15-7=8
15--7= the subtracting beside a negative makes it changes to positive and addition so 15+7=22
