hitunglah luas bangun gabungan di atas!..

dijawab sama carannya di buku tulis ya​

TS = 12 CM

AS = 16 CM

R = 20/2 = 10 CM

MAKA L.GAB :

= 1/2AT + 1/2πR²

= 1/2(12 . 16) + 1/2(3,14(10)²

= 1/2(192) + 1/2(3,14(100)

= 1(192/2) + 1/2(314)

= 1(96) + 1(314/2)

= 96 + 1(157)

= 96 + 157

= 253 CM³

tinggi segitiga = 12 cm

alas segitiga = 16 cm

panjang r lingkaran = d/2 = 20/2 = 10

Luas bagun gabungan:

= Luas segitiga + 1/2 Luas lingkaran

= (1/2 × a × t) + (1/2 × π × r²)

= (1/2 × 12 × 16) + (1/2 × 3,14 × 10²)

= (192/2) + (314/2)

= 96 + 157

= 253 cm²
