Question

pls answer carefully. but the answer should come in 628.57


A tyre has an area of 314 sq.cm. How much distance w
rotations? Take π=3.14​

Answer 1

Step-by-step explanation:

Given ,area = 314sq.cm

Since, area = πr^2

So, 314 = 3.14× r^2

314. = r^2

3.14

So, r^2 =100

r= 10.

Now , distance = 2πr

= 2×3.14×1

= 62.8 cm

628mm
