Answer 1

Answer:

Step-by-step explanation:

Answer 2

clock is in the form of circle

given radius =14cm

in every five minute the degree covered 30degree

so in 20 minute the minute hand covered 120degree

solve-. area of sector =theta/360*×pie r^2


=120*/360*×22/7×14×14

=1/3×22×2×14
=44×14/3
ans =616/3 cm^3
