Diketahui sebuah lingkaran mempunyai jari jari 14 cm, tentukan luas dan kelilingnya! ​

Luas:

L = πr²

L = 22/7 × 14 cm²

L = 22/7 × 14 cm × 14 cm

L = 22 × 2 cm × 14 cm

L = 44 cm × 14 cm

L = 616 cm²

Keliling:

K = 2 × π × r

K = 2 × 22/7 × 14 cm

K = 2 × 22 × 2 cm

K = 44 cm × 2 cm

K = 88 cm

SOAL 1

Keliling Lingkaran

= 2 × π × r

= 2 × 22/7 × 14

= 2 × 22 × 2

= 2 × 44

= 88 cm

Luas lingkaran

= π × r²

= 22/7 × 14²

= 22/7 × 196

= 616 cm²
