Answer:
TSA of a cylinder = 2 × pie × radius × height
154 cm² = 2 ×22÷7× r ×2.3 cm
r = (154 cm² × 7) ÷ ( 2 × 2.3)
r = 1078cm² ÷ 4.6 cm
r = 234.35 cm
Step-by-step explanation:
volume of cylinder = pie × radius × height
= 22÷7 × (234.35)² × 2.3
= 22÷7 × 54919.92 × 2.3
= 396992.564 cm³
= .396992564 m³
