Answer:
1165.73 sq.cm. of newspaper are needed to cover the lateral areas of all five sculptures
Step-by-step explanation:
Diameter of 1 sculpture = 9 cm
Radius of 1 sculpture =[tex]\frac{9}{2}=4.5 cm[/tex]
Slant height of sculpture = l = 16.5 cm
Lateral surface area of each sculpture = [tex]\pi r l = \frac{22}{7} \times 4.5 \times 16.5 =233.3571 cm^2[/tex]
Lateral surface area of 5 sculptures =[tex]233.3571 \times 5 =1165.73 cm^2[/tex]
Hence 1165.73 sq.cm. of newspaper are needed to cover the lateral areas of all five sculptures
