Question

please give me answer of these quesrion with solution​

Answer 1

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
