Step-by-step explanation:

(¡)First convert litres in to cm^3 take it as the volume of the cylindrical container

(¡¡)Then use V=22/7×r^2×h equation and substitute the values to V and r. Then find the value of h

#V=27.72×1000 (V= volume)

# r = 42/2=21 (r = radius)

Elaine has invested $575 in a stock that is expected to double every 8 years. What will be the value of the stock in 16 years?
Sloan [31]
The correct option is D.
The initial value of the stock is $575 and it doubles every 8 years, this means that, in the next eight year the value of the stock will be 2 * 575 = $1150.
This amount too will double in the next eight year and the value will become 2* 1150 = $2,300.
Therefore, in 16 years time the share will be worth $2,300.00.
