Penjelasan dengan langkah-langkah:
Luas = 75.46
(22/7) x r x r = 75.46
r² = 75.46/(22/7)
r² = 75.46 x (7/22)
r² = 528.22/22
r² = 24.01
r = V24.01
r = 4.9
V = akar kuadrat
Diameter = 2 x r
Diameter = 2 x 4.9
Diameter = 9.8 cm
Jawaban:
[tex]Luas \: lingkaran = \pi \times r^{2} [/tex]
[tex]75,46 = \frac{22}{7} \times r^{2} [/tex]
[tex]75,46 \times 7 = 22 \times r^{2} [/tex]
[tex]528,22 = 22 \times r^{2} [/tex]
[tex] \frac{528,22}{22} = r^{2} [/tex]
[tex]24,01 = r^{2} [/tex]
4,9 cm = r
Diameter = 2 × r
= 2 × 4,9
= 9,8 cm
Jadi panjang diameter nya adalah 4,9 cm.
