Question

the diameter of a wheel is 50 cm. how much distance will it cover in 350 revolution
pls don't give any wrong answer​

Answer 1

$d = 50 \\ \\ r = \frac{d}{2} \\ \\ r = \frac{50}{2} \\ \\ r = 25 \\ \\ c = 2\pi \: r \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: c = 2 \times 3.14 \times 25 \\ \\ c = 157 \\ \\ \pink{for \: \: 350 \: \: revolution} \\ \\ 350 \times 157 \\ \\ 54950 \: cm \\ \\ \: \: distance \: \: cover$

Answer 2

Answer:

Diameter = 50 cm

Radius = r = D/2 = 25 cm

So, the circumference of the wheel,

C = 2*22/7*25

C = 157.142857 cm

Now, the distance covered in 350 revolution,

= 55,000 cm

= 550 m

= 0.55 km
