The amount of light passing through each foot the water in the lake = 100% - 60% = 40%
The percent of light passing through 5 feet of water = 0.4^5 = 0.01024 = 1.02%
Answer:
Step-by-step explanation:
Using formula 
a= 650
b= 800
and c is the unkown
You can do this by doing 4 x 384, and you also want to find 4 x 5384 is then all you have to do is multiply the product of that by 5,000. Or to make life easier, do 5 times the product, and then add 3 zeros to the answer.

Answer:
8 cm
Step-by-step explanation:
The formula of circumference is c= πd------(1)
where C = circumference, π = 3.14 and d = diameter
as we know that diameter is equal to d= 2r
put the diameter formula in eq(1)
we get c= π2r-------(2)
from eq (2) separate r means radius
hence, r= c/(π2)------(3)
put the values in eq(3)
and radius is equal to 8 cm.
