Question

Find the distance covered by a wheel of diameter 28 cm in one rotation.


please help​

Answer 1

D = 28 cm

r = 14 cm

CIRCUMFERENCE ( distance covered in 1 rotation ) = π r²

= 22/7 x 14

= 22 x 2

= 44 cm

Answer 2

Given⤵️

▪︎diameter of wheel = 28 cm

▪︎radius = 28 /2 = 14cm

To find⤵️

▪︎ distance travel in one rotation

i.e perimeter of wheel

solution⤵️

➡️ perimeter of wheel = 2 pie × radius

= 2 × 22/7 × 14 = 88cm

hence required distance in one revolutions= 1× 88cm 88cm

hope it helps you ✌
