Answer:
2000.8 m or 2km height
(π 0.07^2)×2000 = 30.78 m^3.
Step-by-step explanation:
The total surface area of a cylinder of radius 7 cm is 880 m^2. Find the height and the volume of the cylinder.
"A cylinder is flat" according to curvature theory (unlike a sphere, where triangle angles can add to more than 180°). So unwrap it and compute area as circumference times height, or height as area divided by circumference. 880m^2 / (2 π 0.07 m) gives height = 2000.8 m or 2km (!!)
The volume of a cylinder is cross section area times height. (π 0.07^2)×2000m = 30.78 m^3.

Answer:
6.13%
Step-by-step explanation:
We are given an investment of $8000 deposited for 4 years. We have to find the effective annual yield for which we will need the interest rate and the compounding period.
Annual interest rate compunded quarterly, r = 6% = 0.06
Compounding period is quarterly, n = 4
Annual EffectiveYield = 
= 0.0613
The annual effective yield is 6.13%
180-(180-49-48)
180-(83)
97
180-((180-141)+(180-76))
180-(39+104)
180-143
137
180-((180-101)+60)
180-(79+60)
180-139

180-(360-109*2)
180-(360-218)
180-142

(180-118)/2
62/2

Hope this helps :)
