Tolonng di jawab ya kak​

Jawaban:

58,875 cm²

Penjelasan dengan langkah-langkah:

Luas = πr² x 3/4

Luas = 3,14 x 5² x 3/4

Luas = 58,875 cm²

r = 5 cm

phi = 3,14

K = (3/4 × 2 × phi × r) + (2 × r)

K = (3/4 × 2 × 3,14 × 5) + (2 × 5)

K = 23,55 + 10

K = 33,55 cm

L = 3/4 × phi × r^2

L = 3/4 × 3,14 × 5 × 5

L = 58,875 cm^2
