Answer:
50/6π
Step-by-step explanation:
Given that:
- Diameter of 20 centimeters
=> the radius is: 20/2 = 10 centimeters
We need to find the area of the clock face
- Area = π[tex]r^{2}[/tex] = π*10*10 = 100π
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 each piece
= The area of the clock face/ 12 equal parts
= 100π / 12
= 50/6π
