Final answer:

The perimeter of a circle with a radius of 35 cm, using the approximation π = 22/7, is 220 cm.

Step-by-step explanation:

To find the perimeter of a circle, which is also known as the circumference, you use the formula C = 2πr, where π (pi) is approximately 22/7 and r is the radius.

Given that the radius (r) of the circle is 35 cm, we can substitute this value into the formula:

C = 2 * (22/7) * 35 cm

Now, calculate the circumference step by step:

C = 2 * 22/7 * 35 cm
C = 44/7 * 35 cm
C = 6.28571429 * 35 cm
C = 220 cm

Therefore, the perimeter of the circle is 220 cm.
