Step-by-step explanation:
if area of circle = pi times radius^2,
area of circle divided by pi = radius^2
so, square root (area of circle divided by 2) = radius.
so, 196pi = m2
approx 616
616=m2
sqrt 616 =m
approx value of radius is 25 or 24.8
pls mark this as brainliestttt
We have the given I = 10^-1 and I₀ = 10^-12.
Simply plugging in the values to the equation, we have:
L = 10log(10^-1/10^-12)
L = 110 Db
The answer is D.
(I used a scientific calculator in solving for L).
Got me there but i think its 325500
Answer: I'm pretty sure that it´s C but Im not sure.
Sorry if that's wrong.
Answer:
It would be option 2.
Step-by-step explanation:
This is because option 1 does not have a irrational number that goes on indefinitely, option three has the square root of 25, which equals 5 meaning it is rational, and the last option also gives us rational choices. Therefore, the only possibility is that it would be option 2.
