Penjelasan dengan langkah-langkah:
Cara satu:
[tex]L = \frac{1}{4} \times \pi \times d {}^{2} \\ L = \frac{1}{4} \times 3.14 \times 94 \times 94 \\ L= \frac{27.745,04}{4} \\ L = 6.936,26 \: cm {}^{2} [/tex]
Cara 2
[tex]L = \pi \times r {}^{2} \\ L = 3.14 \times 47 \times 47 \\ L = 6.936,26 \: cm {}^{2} [/tex]
