We know that in a circle of radius r unit, if an arc of length l unit subtends an angle θ radian at the centre, then
θ = lr.
It is given that r = 75 cm
(i) Here, l = 10 cm
θ = 1075 radian
= 215 radian
(ii) Here, l = 15 cm
θ = 1575 radian
θ = 15 radian
(iii) Here, l = 21 cm
θ = 2175 radian
= 775 radian.
Say my friends how is this looking?
