Answer:
14 cm
Step-by-step explanation:
Find the length of 1 revolution:
100 revolutions = 88 m
1 revolution = 88 ÷ 100 = 0.88 m = 88 cm
Find the radius:
Circumference = 2πr
2πr = 88
r = 88 ÷ 2π = 14 cm
Answer: The radius is 14 cm
hey its 14 m
u wrote cm
It is 14 cm ... not 14 m
1 revolution = 88 ÷ 100
1 revolution= 0.88 m
1 revolution= 0.88m x 100 = 88 cm <== converted to cm
1 revolution= 0.88 m
1 revolution= 0.88m x 100 = 88 cm <== converted to cm
in question it is metres
14 cm = 0.14m <== if you write in m, it will be 0.14 m
(The answer cannot be 14 m)

Answer:
14 m
Step-by-step explanation:
Total Revolutions = 100
= total distance = 88 m
= distance covered in one revolution = 2πr m.
=distance covered in 100 revolution = 2πr . 100
= 88 = 2 . 22/7 . r
= 88 . 1/2 . 7/22 = r
= 14 m
