a=2c+40 z=2c+142 x=2c+165 b=c+82 y=c-20
14+2c+40+2c+142+2c+165+c+82+c-20=1203
c=86 2/3
y=66 2/3
b=168 2/3
x=338 1/3
z=315 1/3
a=213 1/3
16+5x-6=20
5x+16-6=20
5x+10=20
5x=20-10
5x=10
x=10/5
x=2
Answer: 2.
Answer:
B
Step-by-step explanation:
Set up the equation
z = 
Plug in the numbers to find the value of k
3 = 
12 = 4k
3 = k
Solve to find the value of z
z = 
z = 
z = 48/9
z = 16/3
The surface area of a cylinder is 2*pi*r*h(side area)+2*pi*r^2(bases).
When you plug in the values: 2*pi*5*8+2*pi*25 = 80pi+50pi
Answer: 130pi
