Jawaban:
D= 14cm
R= D/2=6cm
T= 21cm
volume
= π × r² ×t
= 22/7 ×7 ×21
= 22×7×21
= 3.234 cm²
Penjelasan dengan langkah-langkah:
diketahui::
D=14 cm R=7 cm
t=21 cm
ditanya:V....?
L.....?
dijawab:
V=π×r²×t
=22/7 × 7 × 7 × 21
=22 × 7 × 21
=154 cm × 21 cm
=3.234 cm
LP=2×π×r×(r+t)
=2×22/7×7(7+21)
=44 × 28
=1.232 cm
