hitung keliling dan luas arsiran

Luas persegi = 28 x 28
= 784

Luas lingkaran
[tex] \frac{1}{2} \times\frac{22}{7} \times 14 \times 14 \\ = \frac{1}{2} \times 616 \\ = 308[/tex]

Luas = 784 - 308
= 476

Keliling = ( 28 + 28 + 28 ) +
[tex](2 \times \frac{22}{7} \times 14 = 28 \times \frac{22}{7} = 88)[/tex]
= 84 + 88
= 172



semoga membantu
