Heya!!
1) Let the length of minor arc be = L
According to the question
L= 2πr/ 6
L = πr / 3
FORMULA
L = angle subtended by minor arc × r
πr/3 = Angle Subtended × r
Angle Subtended by minor arc is = 180/3
= 60°
2) Area of circle is directly proportional to it's area
Corresponding increase in its are is
= (120)² - ( 100)² /( 100)². × 10²
