bag. yg diarsir di lingkaran = 1/4 bag = 90°
1 putaran = 360°
1 π rad = 180°
1° = 60 mt
1° = 3.600 dtk
utk opsi a
= 90° x 3.600
= 324.000" (benar)
utk opsi b
= 90° (benar)
utk opsi c
= 90°/180°
= 1/2π rad
= π/2 rad (salah)
utk opsi d
= 90°/360°
= 1/4 putaran (benar)
utk opsi e
= 90° x 60
= 5.400'
maka, pernyataan yg salah adalah C
