Question

A car travels 0.99km distance,in which each wheel makes 450 complete revolution find the radius

Answer 1

Answer:

Step-by-step explanation:

dist=0.99km=990m

Let in each revolution dist travelled be x

=>450x=990

=>x=11/5

CIrcumference of wheel is =11/5

R=(11/5)/2pi=11/5*7/22=0.7m is the radius

Answer 2

Answer:

0.35

Step-by-step explanation:

0.99 = 450×2π×r

⇒990 = 450×2×227×r

⇒r = 990×7450×2

⇒r = 720 = 0.35m

I hope it helps you...

and 0.35 is the correct ans not 0.7
