Answer:
A) 4
Step-by-step explanation:
There are a couple of ways to get this but this is how I did it:
1. Multiply the second equation by 1/4 to get the same fraction for y as the one in the first equation
1/4 x + 1/8 y = 2
1/4 (1/3 x + 1/2 y = 4)
1/12 x + 1/8 y = 1
2. Subtract the first equation from the new equation
1/12 x + 1/8 y = 1
<u> - 1/4 x - 1/8 y = -2</u>
-1/6 x= -1
3. Divide both sides by -1/6
<u>-1/6</u> x= <u>-1</u>
-1/6 -1/6
x = 6
4. Substitute 4 in for x in the original equation:
1/4 (6) + 1/8y = 2
6/4 + 1/8y = 2
1/8y = 1/2
y = 4

Step-by-step explanation:
Lateral surface area of a cone is expressed as:
L = πr√h²+r²
Given that
r = 11.5/2 = 5.75cm
h=16.6cm
L = 3.14(5.75)√16.6²+5.75²
L = 18.055√275.56+33.0625
L = 18.055*17.56
L=317.0458cm²
Volume = 1/3πr²h
Volume = 1/3π(5.75)²(16.6)
Volume = 1,723.34975/3
Volume = 574.45cm³
