Question

How many times a wheel of radius 28 cm must rotate to go 352 m? (Take π =
22
7 )

Answer 1

Answer:

Step-by-step explanation:

Answer 2

$\huge\sf{Solution}$

From the question it is given that,

• Radius of the wheel = 28 cm

Circumference of the wheel = 2πr

= 2 × 22/7 × 28

= 2 × 22 × 4

= 176 cm

Now we have to find the number of rotation of the wheel,

= Total distance to be covered/ circumference of wheel

= 352 m/176 cm

= 35200 cm/ 176 cm

= 200
