Answer:
V= 452.39cm³ (to 2 d.p. )
S.A. = 326.73cm² (to 2 d.p. )
Step-by-step explanation:
Vcylinder = π r² h = π (4)² (9) = 144 π = 452.3893421cm³ = 452.39cm³ (to 2 d.p. )
S.A. cylinder = 2π r h + 2π r² = 2π (4)(9) + 2π (4)² = 104π = 326.725636cm² = 326.73cm² (to 2 d.p. )
Multiplying decimals is basically the same thing as multiplying whole numbers, but a little tougher. For example, 3 X 2 = 6, which is quite easy, but yoou might need more education to solve 3.6 X 2.6 = 9.36
