Question

how many times a wheel of radius 28cm must rotate to go 352 m? ​

Answer 1

Step-by-step explanation:

circumference-2πr

2. multiply 22over7 multiply 28=176cm

Total distance=352m

352*100=35200cm

no.of rotation=35200 divided by 176

=200 rotations

Answer 2

ᗩᑎᔕᗯᗴᖇ:

• ❇️ Radius of circle = 28cm

• ❇️ Circumference of circle = 2pie r

• ❇️ = 2 × 22/7 × 28

• ❇️ 176cm

• ❇️ Therefore, circumference is 176cm

• ❇️ Metres it should rotate = 352m

• ❇️ 352m = 35, 200

• ❇️ = 35,200 ÷ 176

• ❇️ = 200

• ❇️ Hence, it will take 200 rotations.
