Answer:
283 square inches
Step-by-step explanation:
Stacking 8 plates with height of each being 0.5 inch will form a cylinder with height 4 inches.
The radius of the cylinder is half the diameter
The total surface area of this cylinder is:
We substitute the values to get:
She will need approximately 283 square inches of wrapping

Look at the multiples of the two numbers and find the lowest one that matches e.g.
7 = 7, 14, 21, 28
4= 4, 8, 12, 16, 20, 24, 28
28 is the LCM of 7 and 4
Answer:
x=0 and y=4 thats where the points meet
Step-by-step explanation:
solution of x and y:
both equations equal to y so you can put them together
3/5x+4=-x+4
separate the variables and numbers...
1.6x=0
x=0
y=4
if ur using a graph, use the y intercept (0,4) for your first point
then, using y=-x+4, make -x a fraction -1/1
by using rise/run go down one unit from (0,4) since its negative 1
then one unit to the right from where you are
you should be able to connect the points for the first equation
find the second equation on your own now:)
Remember, the formula for circumference is c = πd. If your diameter is 8 inches, then your circumference is 8π inches.
