Question

how many times A wheel of radius 28cm first rotate to go to 352 M

Answer 1

radius of wheel = 28 CM
circumference of wheel = 2 ×22/7 ×28
=176cm

distance the wheel rotate =352 m or 35200cm
therefore total times will rotate = 35200/176
= 200
therefore the wheel rotate 200 times to go 352.

Answer 2

Answer:

radius of wheel =28/100 =7/25

The circumference of wheel =

$2\pi \: r$

=2×22/7×7/25

=44/25

=44/25 wheel rotate in 1 m.

So, =》352 rotate

=》1×352×44/25

=》8×25 =200

=》200 times wheel rotate
