First we need to know the surface area of the package:
2(lw) + 2(lh) + 2(wh)
2(8*11) + 2(11*2) + 2(8*2)
2(88) + 2(22) + 2(16)
176 + 44 + 32
252 square inches needed
Wrapping paper is in feet, so convert it to inches before finding the area.
1' = 12"; 2' = 24"
12* 24 = 288 square inches.
So, yes there is enough paper to cover all sides of the gift if there are no overlaps.
Answer:
70
Step-by-step explanation:
Chem : Phy = 3: 2
Since we have 105 pupils studying Chem and let's say we have x students stuyding Phy.
We have :
x=70
f(x) + n - move the graph n units up
f(x) - n - move the graph n units down
n · f(x) - stretch by n in the y-direction
1/n · f(x) - compress by n in the y-direction

First:
Second:
The shape is a square, therefore, all sides are equal.
The edge of the circle touches the edge of the square, and thus, one side of the square can be considered to be the same length as the diameter of the circle.
The formula for circumference is :
2"pie"r
Perimeter = 40ft.
Therefore each side = 10ft.
Therefore diameter = 10ft.
Therefore radius = d/2 = 10/2 = 5 ft.
Therefore circumference = 2"pie"5 ft = 10"pie" ft
(don't forget the unit of measurement!)
Hope this helped ~
