Question

The circumference of a circle of radius r is given by the polynomial 2​r, where is an irrational number. for an approximation of ​, use 3.14. find the circumference of a circle with radius 17 cm.

Answer 1

The circumference of a circle with a radius of 17 cm, using an approximation of π as 3.14, is 106.8 cm.

Step-by-step explanation:

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. In this case, the radius is 17 cm. We can use an approximation for π by using the value 3.14.

To find the circumference, we substitute the radius value into the formula and calculate: C = 2 x 3.14 x 17 cm = 106.8 cm.

Therefore, the circumference of a circle with a radius of 17 cm, using an approximation of π as 3.14, is 106.8 cm.
