The radius of front wheel is 21 cm. the arc lenght of the training wheel which is subtended by angle 60° is 6.25 cm. the front wheel of the bike makes 40 complete rotations. find the number of complete rotations made by the training wheel.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
