Step-by-step explanation:
First, you'd get the area of the circle, then multiply it by two (there's two ends to a cylinder)
so (pi)(R^2)
If 8 is the diameter, then 4 is the radius (r=1/2d)
3.14{pi}*16{4 squared}+=50.27
(50.27*2)= 100.54
Now, we need to find the area of the side of the cylinder. We have the given height of 16.8, and now we need to find the length. In order to do that, we must find the perimeter/diameter of the circle with the formula of Pi*Diameter.
if the diameter of the circle is 8, then 3.14*8=25.12.
25.12*16.8=422.016
now we need to add the area of the circles to get total surface area.
100.54+422.016= 522.556cm^2
I hope this helps!
Addition Property of Equality
Step-by-step explanation:
The equations are given as;
2x+2y=14----(i)
y-x=5 ?-------apply addition property of equality
y-x+x=5+x
y=5+x -------use this expression in equation (i)
2x +2(5+x)=14 ----------open brackets on the left side
2x+10+2x=14 -------collect like terms
4x+10=14
4x=14-10
4x=4
4x/4=4/4
x=1
y-1=5
y=6
