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 diameter of a bubble containing 1,000 cm³ of air is 12.4 cm.
Sphere is a three dimensional object with a shape like that of a ball.
The volume of a sphere is given by:
Volume = (4/3)πr³
where r is the radius of the sphere.
Given that the sphere has a volume of 1000 cm³, hence:
1000 = (4/3)πr³
r³ = 238.73
r = 6.2 cm
Diameter = 2 * r = 2 * 6.2 = 12.4 cm
The diameter of a bubble containing 1,000 cm³ of air is 12.4 cm.
