Nomor 1 :

¾ lingkaran + luas segitiga =

(¾ × π × r × r) + (½ × a × t) =

(¾ × 22/7 × 14 × 14) + (½ × 14 × 14) =

(3 × 11 × 14) + (7 × 14) =

(3 × 154) + 98 =

462 + 98 =

560 cm²

Nomor 2 :

¾ lingkaran + persegi =

(¾ × π × r × r) + (s × s) =

(¾ × 22/7 × 14 × 14) + (14 × 14) =

(3 × 11 × 14) + 196 =

(3 × 154) + 196 =

462 + 196 =

658 cm ²

Semoga membantu.

Sukses selalu.

1) DIKET :

R = 14 CM

DIT :

LUAS ?

L = 3/4 L + LS

= ( 3/4πR² ) + ( 1/2AT )

= ( 3/4 . 22/7 . 14² ) + ( 1/2 . 14 . 14 )

= (3/4 . 22/7 . 196) + (1/2 . 196)

= (3/4 . 22 . 28) + 98

= 3/4 . 616 + 98

= 3 . 154 + 98

= 462 + 98

= 560 CM²

2) DIKET :

R / S = 14 CM

DIT :

LUAS ?

= 3/4L + L.PERSEGI

= ( 3/4πR² ) + (S²)

= ( 3/4 . 22/7 . 14² ) + ( 14² )

= ( 3/4 . 22/7 . 196 ) + 196

= ( 3/4 . 22 . 28 ) + 196

= 3/4 . 616 + 196

= 3 . 154 + 196

= 462 + 196

= 658 CM²
