Answer 1

Given

Length of minute hand =14cm (Radius)

Given

Length of minute hand =14cm (Radius)

Angle created by minute hand in 20 min=120

(360/60=6 in one min 20x6=120)

Area swept =angle of sector /360 x pi r²

=120/360 x22/7 x 14x14

=205.334 [approx.] cm²

This is ur ans hope it will help you

Answer 2

Answer:

AS THE ANGEL BETWEEN 10AM AND 10:20 AM IS 180 DEGREE THEN,

THE AREA MADE BAY MINUTE HAND WILL BE PIE R SQUARE BY 2 THEN,

=22×14×14÷14

=22×14×2÷2

=22×14

=308cm SQUARE
