The diameter of a circle is 8 centimeters. A central angle of the circle of the circle intercepts an arc of 12 centimeters. What

Studentka2010 [4]

Answer:

The measure of the angle is $3\ radians$

Step-by-step explanation:

we know that

The formula to calculate the arc length of a circle is equal to

$L=r\theta$

where

r is the radius of the circle

$\theta$ is the measure of the angle in radians

In this problem we have

$L=12\ cm, r=8/2=4\ cm$

substitute in the formula and solve for $\theta$

$12=4\theta$

$\theta=12/4$

$\theta=3\ radians$

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.
