Penjelasan dengan langkah-langkah:
L = ¾ x πr²
= ¾ x 3,14 x 4 x 4
= 37,68 cm²
K = ¾ x πd
= ¾ x 3,14 x 8
= 18,84 cm
LP . 3/4LINGKARAN :
= 3/4πr²
= 3/4(3,14(8/2)²
= 3/4(3,14(4)²
= 3/4(3,14(16)
= 3/4(50,24)
= 150,72/4
= 37,68 CM²
K . 3/4LINGKARAN :
= 3/4πd
= 3/4(3,14(8)
= 3/4(25,12)
= 75,36/4
= 18,84 CM
