Answer:
Step-by-step explanation:
area of a cylinder = (area of a circle) times the (height)
area of a cylinder = π radius² × height
radius = 57 cm height = 40 cm
area of a cylinder = π 57² cm² × 40 cm
= π (57² × 40) cm³
= π ( 57 × 57 × 40) cm³ 57x57 = 399 + 2850 = 3249
= π (3249 × 40) cm³
= 129969π cm³ π = 3.14
= 129969 × 3.14 cm³
= 408,074.4 cm³ < ----------------- Final Answer
