Answer 2

✨Here’s your answer....✨


(i) TSA of fig. = TSA of cylinder + 2(TSA of cones)

Diameter = 8m
Radius (r) = Diameter/2 = 8/2 = 4m
Height (h) = 8m

TSA of cylinder = 2πr (h + r)
= 2 × 3.14 × 4 ( 8 + 4 )
= 25.12 ( 12 )
= 301.44 m²

Diameter = 8m
Radius (r) = Diameter/2 = 8/2 = 4m
Length (l) = 6m

TSA of cone = πr (l + r)
= 3.14 × 4 × ( 6 + 4 )
= 12.56 ( 10 )
= 125.6 m²

TSA of fig. = TSA of cylinder + 2(TSA of cones)
= 301.44 + 2 ( 125.6 )
= 301.44 + 251.2
= 552.64 m²

(ii) Volume of fig. = Volume of cylinder + 2(Volume of cones)

Diameter = 8m
Radius (r) = Diameter/2 = 8/2 = 4m
Height (h) = 8m

Volume of cylinder = πr²h
= 3.14 × 4 × 4 × 8
= 402.12 m²

Diameter = 8m
Radius (r) = Diameter/2 = 8/2 = 4m
Height (h) = 6m

Volume of cone = πr ² h/3
= 3.14 × 4 × 4 × 6/3
= 50.24 × 2
= 100.48 m²

Volume of fig. = Volume of cylinder + 2(Volume of cones)
= 402.12 + 2 (100.48)
= 402.12 + 200.96
= 603.08 m²


Hope it helps you✌✌ ..... plz mark me brainiest
