luas lingkaran dengan diameter 49 cm adalah
![]()
~ Lingkaran
===================================
Diketahui:
d = 49 cm
Ditanya
L ?
Jawab:
[tex] \sf \: L = \frac{1}{4} \times \pi \times {d}^{2} \\ \\ \sf \frac{1}{4} \times \frac{22}{ \cancel7} \times \cancel{49} \: {}^{7} \times 49 \\ \\ \sf \frac{22 \times 7 \times 49}{4} \\ \\ \sf \frac{7.546}{4} = 1886,5 \: cm \\ \\ \\ \\ \\ \sf \red{ - cmiiw - }[/tex]
Materi : Bangun Datar
Luas Lingkaran
L = π × r²
L = 22/7 × 24,5 cm × 24,5 cm
L = 22 × 3,5 cm × 24,5 cm
L = 77 cm × 24,5 cm
{ L = 1.886,5 cm² }
Semoga bisa membantu
