Question

How many times the wheel of radius 28cm must rotate to go 176m?
(Take π = 22/7

Answer 1

radius of

wheel = 28 cm

Circumference of wheel = 2πr

= 2 × 22/7 × 28 cm

= 2 × 22 × 4 cm

= 176 cm

Total distance = 352 m = 35200 cm

Number of times the wheel should rotate = Total distance covered by wheel / Circumference of the wheel

= 35200/176

= 200 hope it helps you please mark me as brainliest please

Answer 2

Step-by-step explanation:

.10 rotations. Step-by-step explanation: The circumference of a circle= Distance travelled in one rotation.

circumference= 2πr , where r= radius

2×(22/7)×28=176cm=17.6m

distance travelled in 1 revolution=17.6

distance travelled in 10 revolutions= 17.6×10=176 m
