Question

find the area of diameter 112cm. finf how many complete revolution must it take to cover 880 m.

Answer 1

Hey friend here is ur solution...

______________________________


Given diameter of circle = 112cm =1.12 m


Hence Area= (π/4)d²

=(π/4)*1.12*1.12


= 0.985 m²



Now its perimeter=πd
=π*1.12
=3.518m

Hence revolution in 880m

= 880/3.518

=250.14

Approx 250 revolution may takes place..
