Question

The distance covered by a wheel in one revolution is 88 cm, then the
diameter of the wheel is_______ [π=22/7]

A) 28CM
B) 14CM
C) 7CM
D) 70CM​

Answer 1

Answer:

28 cm

Step-by-step explanation:

As it is given that two pie r is equal to 88 after that solbe that equation

Answer 2

Answer:

B: 28 cm

Step-by-step explanation:

distance in one revolution = circumference of circle

therefore, circumference =88 cm

circumference = 2×pi ×radius

88 =2 ×22/7 × r

88 ×7/ 22 ×2 = r

14 = r

diameter =2r = 2×14 = 28 cm
