There are several different angles associated with circles. Perhaps the one that most immediately comes to mind is the central angle. It is the central angle's ability to sweep through an arc of 360 degrees that determines the number of degrees usually thought of as being contained by a circle.

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large

sergey [27]

Answer:

R = 10 cm

Step-by-step explanation:

The area of a spherical shape is given by :

$A=4\pi r^2$

Where

r is the radius of the sphere

ATQ,

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble.

The radius of each small bubble is 5 cm

Using the given condition,

$4\pi R^2=4\times (4\pi r^2)\\\\R^2=4r^2\\\\R=\sqrt{4r^2} \\\\R=2r\\\\R=2\times 5\\\\R=10\ cm$

So, the radius of the large bubble is equal to 10 cm.
