Please tell me the answer of this question [step by step explanation]​

Answer»

Answer:

a)628m

b) 200m

Step-by-step explanation:

a) distance travelled :

r=d/2

r=200/2=100

circumfrence=2πr

2x3.14x100

=628m

b) 1min 10sec=70sec

distance travelled in 20 sec=628

distance travelled in 70 sec=2198

total rounds =2198/628=3.5

or 3 and 1/2 round

therefore DISPLACEMENT would be DIAMETER of the grond =200m

(displacement is the SHORTEST route from the point to initial position)
