Luas 1/4 lingkaran - luas segitiga luas 1/4 lingkaran = phi x 10 cm x 10 cm x 1/4 = 78,5 cm2 luas segitiga = 10 cm x 10 cm x 1/2 = 50 cm2 78,5 cm2 - 50 cm2 = 28,5 cm2
=1/4 x 314
=78,5
lsegitiga = 1/2x10x10
=50
ltembereng =ljuring-luas segitiga
=78,5-50
=28,5
luas 1/4 lingkaran = phi x 10 cm x 10 cm x 1/4 = 78,5 cm2
luas segitiga = 10 cm x 10 cm x 1/2 = 50 cm2
78,5 cm2 - 50 cm2 = 28,5 cm2
