A wheel made 50 revolutions, it covered a distance of 55 m. Find the radius of the wheel. (Take = 22/7)

Jawaban:

radius is 0.175 m

Penjelasan dengan langkah-langkah:

we know if wheel made 50 revolution and mileage is 55.

first we have to find around the wheel

$55 div 50 = 1.1m$

than we have to find diameter

$pi times d = 1.1 \ frac{22}{7} times d = 1.1 \ 22d = 7.7 \ d = frac{7.7}{22} \ d = 0.35$

$d = 2r \ 0.35 = 2r \ r = 0.175$
