Question

Find the distance covered in 10 rotation by the front wheel of the road roller whose diameter is 4 metre

Answer 1

Answer:

125.7 m

Step-by-step explanation:

radius = 4/2 = 2m

thus distance covered in 1 rotation

= circumference of the wheel

= 2×22/7×2

=88/7

=12.57 m

thus distance of 10 rotation

= 12.57 × 10

=125.7 m

: the distance covered in 10 rotation is 125.7 my.

Answer 2

Answer:

for one revolution::2×3.14× 2

4×3.14

=12.56.

for 10 revolutions, 12.56×10

=125.6
