Answer 2

Answer:

100

Step-by-step explanation:

as the daimeter is 2.1m

therefore the radius becomes 2.1/2

as the cartwheel runs about its circumference therefore we need to find the circumference of the wheel

c=2πr

2*22/7*2.1/2

we get 6.6 m

as the cart runs 660m

number of revolutions becomes distance/circumference

which is660/6.6=100 revolutions
