Answer:
84.85cm
Step-by-step explanation:
Let the sides of the square be x
The perimeter of the square = 4x
Get x using the pythagoras theorem
x^2 + x^2 = 30^2
2x^2 = 900
x^2 = 450
x = 21.21cm
Perimeter of the plate = 4(21.21)
Perimeter of the plate = 84.85cm
A can is a cylinder shape.
Volume of a cylinder = PI x r^2 X h
r is the radius and h is the height.
The diameter is given as 3.8, the radius is half that: 3.8 /2 = 1.9
Height is given as 6.5
Volume = 3.14 x 1.9^2 x 6.
Volume = 73.6801 cubic inches.
Rounded to the nearest tenth = 73.7 cubic inches.
