Answer:
1.Answer: Total Area = 76 π or 238.76 cm^2
Step-by-step explanation:
Formula: 2πr^2 + πrh ; r = radius and h = height
Total Area of Milk Can = 2π (4cm)^2 + π (4cm) (11cm)
= 76 π or 238.76 cm^2

3.The dimensions of a cube (length, width, and height) are equal.
A cube has six faces, so, if the area is 96cm^2, then, the Area of one of the faces will be 96cm^2 ÷ 6 = 16cm^2
since Area = L x W = L2, then L = √16cm^2 = 4cm.
