Answer:
A is correct
Step-by-step explanation:
In this question, we are concerned with. calculating the diameter of a bubble given the volume of the bubble.
Since we have assumed the bubble to be a perfect sphere, it’s volume V = 4/3 * pi * r^3
Plugging the value of V = 1000cm^3 , we have
1000 = 4/3 * pi * r^3
3000/4pi = r^3
r^3 = 238.732
r = cube foot of 238.732
r = 6.20cm
This is same as 6.2cm
The solution possible can be correct by dividing both sides by -5 ;Sooo x>-5.....
Answer:
4
Step-by-step explanation:
hope this helps and have a great day
Step-by-step explanation:
x^2 + y^2 = r^2 --> r =
=
cos = x /r = -4 /
sin = y /r = 5/
tan = sin /cos = -5 /4
