Question

Find the distance covered by a wheel of a car in 550 revolutions if the diameter of a wheel is 87
​

Answer 1

Step-by-step explanation:

number of revolutions(n) = 550

diamter of the wheel = 87

then radious (r) = diameter/2 = 87/2

perimeter of wheel =2πr. ( where r = radious)

= 2×22/7 × 87/2. = 87×22/7

distance cover by the wheel = perimeter of the wheel × number of revolution

or = 2π r n

= 87×22/7 × 550= 150385.71

_______________________________

Distance covered in one revolution =πD

= $\huge\frac{22}{7} \times 77 = 242cm$

Distance covered in 500 revolutions

=500 x 242

=121000cm

=121000cm= 1210m

= 1210m.
