Juan ran all the way around a circular track one time. The diameter (d) of the track is 60 meters. The formula for circumference

kenny6666 [7]

circumference is C = πd, d = diameter.

we know the diameter is 60, so one time around the track is just C = π60 which if you plug that in your calculator, we get C ≈ 188.4955592153876.

Answer:

P = 15.71 cm

Step-by-step explanation:

Given that,

The diameter of the semicircle, d = 10 cm

Radius, r = 5 cm

The perimeter of the semicircle is given by :

$P=\dfrac{\text{The perimeter of the circle}}{2}\\\\=\dfrac{2\pi r}{2}\\\\=\pi r\\\\=3.142\times 5\\\\=15.71\ cm$

So, the perimeter of the semicircle is 15.71 cm.
