Pertanyaan

Sebuah tabung berdiameter 14 dm,tinggi 28 dm berapa m³ volume tabung??
Pakai cara..

Answer 1

d = 14 cm
r = 14 ÷ 2 = 7 cm

V = π r kuadrat × t
= 22/7 × 7 × 7 × 28
= 22/7 × 49 × 28
= 154 × 28
= 4.312 dm3
= 4,312 m3

Answer 2

Diameter = 14 dm
Jari-jari = 7 dm

Volume tabung = phi × r^2 × t
= 22/7 × 7 × 7 × 28
= 154 × 28
= 4.312 dm^3 = 4,312 m^3

SEMOGA MEMBANTU :)
