Formula =
1. Perimeter of Semi Circle = r(pie + 2)
2. Area of Semi Circle = 1/2 pie r²
Since Protractor Is Shape Of Semi Circle
Perimeter of Semi Circle(protractor) = r(pie + 2)
36 = r(22/7 + 2)
36 = r[(22 + 14)/7]
36 = r[(36)/7]
r =36 * 7 / 36
r = 7 cm
Area of Protractor = 1/2 Pie r²
= 1/2 * 22/7 * 7 * 7
= 11 * 7
= 77cm²
