What is the measure in radians for the central angle of a circle whose radius is 5 and intercepted arc length is 7.2? Round your
Olegator [25]

Answer:

0.46\pi\ radians

Step-by-step explanation:

step 1

Find the circumference

The circumference of a circle is equal to

C=2\pi r

we have

r=5\ units

assume

\pi=3.14

substitute

C=2(3.14)(5)=31.4\ units

step 2

Find  the measure in radians for the central angle of a circle whose radius is 5 and intercepted arc length is 7.2 units

Remember that

The circumference of 31.4\ units subtends a central angle of 2\pi \ radians

so

using proportion

Let

x-----> the central angle in radians

\frac{2\pi}{31.4}=\frac{x}{7.2} \\ \\x=2\pi (7.2)/31.4\\ \\x=0.46\pi\ radians
