Question

a cylindrical soup Can is 15.4 CM diameter and 20 CM in length what is the area of the level that covers the side of the can​

Answer 1

Answer:968cm²

Explanation:D=15.4

D=2r

r=d/2

=15.4/2

r=7.7

csa=2πrh

=2×22/7×7.7×20

=968cm²

Answer 2

Area of the label covering the side of the can is 968 cm².

Length of the can = l = 20cm  (Given)

Diameter of the cylindrical can = d = 15.4cm  (Given)

Radius of the can = r = d/2 = 15.4/2 = 7.7cm

Area of the label = Curved surface area of the can

CSA = 2πrh

Therefore,

= 2 × 22/7 × 7.7 × 20

= 968 cm

Therefore, the area of the label covering the side of the can is 968 cm².
