Question

The radius of a tractor wheel is 77cm. Calculate the distance covered by it in 35 rotations?

Answer 1

Answer:

2πr

2×22/7×77

2×22×11

44×11

484×35

16940

Answer 2

Answer:

GIVEN -: RADIUS OF WHEEL = 77

TO FIND -: DISTANCE COVERED IN 35 ROTATIONS

SOLUTION -: DISTANCE COVERED IN ONE ROTATION

=

CIRCUMFERENCE OF THE WHEEL THEREFORE,

DISTANCE COVERED IN 35 ROTATIONS

=

35 × CIRCUMFERENCE OF CIRCULAR WHEEL

=> 35×πr²

=> 35 ×22/7×77×77

=> 35 ×22×11×77

=> 770 × 847

=> 6,52,190 cm²

ANS => DISTANCE IN 35 ROTATION IS 6,52,190 cm²

I HOPE IT HELP YOU ✌️✌️✌️✌️✌️

THANKS YOU
