Answer 1

A status bar is a graphical control element which poses an information area typically found at the window's bottom. It can be divided into sections to group information. Its job is primarily to display information about the current state of its window, although some status bars have extra functionality.

Hope so it will help...

Answer 2

Let the radius of the two circles are a and b cm

The circles touch each other externally.

So, the distance between their centers =a+b

a+b=14 ................... (1)

Sum of their areas =πa² +πb²

πa² +πb² =130π

a² +b² =130 .................... (2)

From equation (1),

b=14−a ............. (3)

From (2) and (3),

a² +(14−a) ² =130

a² +a² +196−28a=130

2a² +66−28a=0a² +33−14a=0a² −11a−3a+33=0

(a−11)(a−3)=0

a=3,11

If a=3, then b=14−3=11

If a=11, then b=14−11=3

So, the radius of the two circles are 3 and 11 cm

And their diameters are 6 and 22 cm.
