Question

What should be the radius of a wheel if it is required to cover 23.32 m in 10 complete rotations? (3)
(Take π =22/7)

Answer 1

Answer: 34

Step-by-step explanation:

Answer 2

Answer:

37.1cm

Step-by-step explanation:

$revolutions = \frac{distance}{circumference}$

let the radius be r

circumference = 2πr

distance given = 23.32 m = 2332cm

revolutions given = 10

putting these values in the formula, we have,

$10 = \frac{2332}{2\pi \: r} \\ \\ r = \frac{2332}{10 \times 2\pi} \\ \\ r = \frac{2332 \times 7}{10 \times 2 \times 22} \\ \\ r = 37.1cm$
