If the diameter of the semicircle is 1.7 centimeters, what is the perimeter of this figure in centimeters? 25.7 cm 26.669 cm 29.338 cm 5.069 cm

The circumference of the circle is calculated through the equation,

C = 2πr

Since, we are referring to only a semicircle, it becomes,

C = πr

Substituting the known variable,

C = π (1.7 cm/2) = 2.669 cm

Then, we add the diameter to the calculated circumference to get the perimeter.

P = 2.669 cm + 1.7 = 4.369 cm.
