Question

find the distance covered by wheel of a bus in 2ooo revolution if the diameter of the wheel is 98 cm

Answer 1

first we hv to find the circumference of the wheel
so
we hv diameter 98cm
$\pi \times d$

22/7x98
22×14
308
now no. of revolutions
308×2000
616000
hope it helps you frnd

Answer 2

as d = 98
so the radius of the wheel is 49 cm
circumference = 2πr
2*22/7*49
so the circumference is equal to 308 cm
in 2000 revolutions, distance covered= 2000* circumference of the wheel
2000*308
the distance covered by the wheel in 2000 revolutions is equal to 616000cm
