luas lingkaran = 22/7 x 21² = 1386 cm²
sudut O = 90 derajat
Luas Juring/1386 = 90/360
Luas Juring / 1386 = 1/4
Luas Juring = 1/4 x 1386Luas juring = 346,5 cm²
Luas Segitiga = 1/2 x alas x tinggiLuas Segitiga = 1/2 x 21 x 21
Luas Segitiga = 220,5 cm²
Luas Tembereng = Luas Juring - Luas SegitigaLuas Tembereng = 346,5 cm2 - 220,5 cm2
Luas Tembereng = 126 cm2
