Sadie wants to draw a clock face on a circular piece of cardboard. If the clock face has a diameter of 20 centimeters and is divided into congruent pieces so that each sector is 30 degrees, what is the area of each piece?

50/6π

Step-by-step explanation:

Given that:

=> the radius is: 20/2 = 10 centimeters

We need to find the area of the clock face

She divided into congruent pieces so that each sector is 30 degrees it means that clock face (360 degrees) is devided into:

= 360degree / 30 degree

= 12 equal parts

= The area of the clock face/ 12 equal parts  

= 100π / 12

= 50/6π

on your paper it doesn't say the answer but the the answer is altitude
