Find the length of a circle with a radius of 5cm. Find the arc length env. at 36 degrees.

Let’s take the default value of π equal to 3.14.

Let us determine how many centimeters will express the length of our circle, when from the condition of the task we know that its radius is five centimeters:

3.14 * 2 * 5 = 31.4.

Answer: Our circumference will be 31.4 centimeters.

Let’s find out how many times the angle is 36 ° less than the angle of 360 °:

360: 36 = 10.

Determine how many centimeters will express the length of the arc:

31.4: 10 = 3.14.

Answer: The arc length is 3.14 cm.
