Penjelasan dengan langkah-langkah:
Keliling lingkar topi = keliling lingkaran
22 cm = 2 x π x r
22 cm = 2 x [tex]\frac{22}{7}[/tex] x r
22 cm = [tex]\frac{44}{7}[/tex] x r
r = 22 cm : [tex]\frac{44}{7}[/tex]
r = 22 cm x [tex]\frac{7}{44}[/tex]
r = 3,5 cm
Volume topi = 1/3 x luas alas x tinggi
Volume topi = 1/3 x 22/7 x 3,5 cm x 3,5 cm x 15 cm
Volume topi = 192,5 cm³
Jadi volume topi adalah 192,5 cm³
Kll = 2 x πr
22 = 2 x 22/7 x r
22 = 44/7 x r
r = 22 x 7 ÷ 44
V = ⅓ πr²t
= ⅓ x 22/7 x 3,5 x 3,5 x 15
= 192,5 cm³
