Question

wheel of a car rotated 1000 times in travelling a distance of 1.76 km. Find the radius of the wheel Take a = 22/7​

Answer 1

Answer:

Step-by-step explanation:

Distance=no. Of revolution × circumference of wheel

1.76km=1000*C

1.76*1000m=1000*C

1.76m=2πr

176cm=2*22/7*r

(176*7)/2*22 =r

r=4*7cm=28cm

Answer 2

Answer

2×π×r÷1.76=1000

2×π×r=1760

2×22/7×r=1760

r=880×7/22

r=40×7=280
