Question

A wheel makes 1000 revolution in covering a distance of 88 km the radius of wheel​

Answer 1

Answer:

14 m

Step-by-step explanation:

Circumference of circle = distance covered / revolutions taken

= 88km / 1000

= 0.088 km

= 88 m

Circumference of circle = 2× 22/ 7 ×r

2×22/7×r=88

r=88×7/22×2

r=14 m

Answer 2

Step-by-step explanation:

Dist. covered in 1000 revolition = 88 km

Dist. Covered in 1 revolution = 88/1000

Since,

Dist. covered = circumference of

in 1 revolution the circle

88/ 1000 = 2πr

r. = 88/(1000×2π)

= r = (88 × 7)/(1000 × 22 × 2)

= r = 7/ 500 km

= r = 7/500 × 1000 m

r = 14 m

Hence, the radius of the wheel is 14 m .
