Jawab: A. L= 706,5 [tex]cm^{2}[/tex]
B. L = 1884,785 [tex]cm^{2}[/tex]
C. L = 15.386 [tex]cm^{2}[/tex]
Penjelasan dengan langkah-langkah:
A. [tex]L=\pi.r^{2}[/tex]
L= 3.14 x 15 x 15
L= 706,5 [tex]cm^{2}[/tex]
B. [tex]L=\pi.r^{2}\\[/tex]
L=3.14 x 24.5 x 24.5
= 1884,785 [tex]cm^{2}[/tex]
C. [tex]L=\pi.r^{2}\\[/tex]
L= 3.14 x 70 x 70
= 15.386 [tex]cm^{2}[/tex]
