Pembahasan Soal:

i). Panjang Busur

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell fraction numerator 90 degree over denominator 360 degree end fraction cross times 2 cross times straight pi cross times straight r end cell equals cell 1 fourth cross times 2 cross times straight pi cross times straight r end cell row blank equals cell 1 fourth cross times 2 cross times 22 over 7 cross times 7 end cell row blank equals cell 11 space end cell end table end style

ii) Panjang Busur

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell fraction numerator 60 degree over denominator 360 degree end fraction cross times 2 cross times straight pi cross times straight r end cell equals cell 1 over 6 cross times 2 cross times straight pi cross times straight r end cell row blank equals cell 1 over 6 cross times 2 cross times 22 over 7 cross times 21 end cell row blank equals 22 end table end style 

iii) Jari-jari

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell fraction numerator 120 degree over denominator 360 degree end fraction cross times 2 cross times straight pi cross times straight r end cell equals cell 1 third cross times 2 cross times straight pi cross times straight r end cell row 88 equals cell 1 third cross times 2 cross times 22 over 7 cross times r end cell row 42 equals r end table end style

iv) Sudut

Error converting from MathML to accessible text.

v) Jari-jari

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell fraction numerator 72 degree over denominator 360 degree end fraction cross times 2 cross times straight pi cross times straight r end cell equals cell 1 fifth cross times 2 cross times straight pi cross times straight r end cell row 1256 equals cell fraction numerator 72 degree over denominator 360 degree end fraction cross times 2 cross times 3.14 cross times straight r end cell row 1000 equals straight r end table end style
