An ox in a oil processing apparatus is tethered to a rope 3m long .How much distance does it cover in 14 rounds?

Find the circumference. Multiply it by 14.

2π*3 * 14

To calculate the distance covered by the ox in 14 rounds, we first need to find the distance covered in one round, and then multiply it by 14.

In one round, the ox moves along the circumference of a circle with a radius equal to the length of the rope, which is 3m. The formula to calculate the circumference of a circle is:

C = 2πr

where C is the circumference and r is the radius.

Substituting the values, we get:

C = 2π(3)
C = 6π

So, in one round, the ox covers a distance of 6π meters.

To find the total distance covered in 14 rounds, we multiply the distance covered in one round by 14:

Total distance = 6π * 14

Now, to get the value, we need to approximate the value of π. The value of π is approximately 3.14. Substituting this value, we can calculate the total distance covered:

Total distance = 6 * 3.14 * 14
Total distance = 263.76 meters

Therefore, the ox covers approximately 263.76 meters in 14 rounds.
