Sectors of circle. east points, this is due tomorrow help is appreciated
PSYCHO15rus [73]

By knowing the circumference of the base of the cone, we see that the radius is 4 centimeters.

<h3>How to find the radius of the cone?</h3>

Notice that in the first figure, the length of the arc AB is L = 8π cm.

Then, that arc will be the bottom part of the cone. Then we can see that the circumference of the base of the cone will be equal to the length of the arc.

And remember that for a circle of radius R (like the base of the cone), the circumference is:

C = 2πR.

Then we will get:

8π cm = C =  2πR

( 8π cm)/ 2π = R

4cm = R

The radius of the cone is 4cm.
