Solution :
2a + 2b = 7 ...1)
4a + 3b = 12 ...2)
In equation, 1)
a = (7 - 2b)/2 ...3)
Putting value of a in equation 2) we get :
4 × (7 - 2b)/2 + 3b = 12
2( 7 - 2b ) + 3b = 12
14 - 4b + 3b = 12
b = 2
Putting value of b in 3) we get :
a = ( 7 - 2×2)/2
a = 3/2 = 1.5
Now,
2x - 3y = 16 ...5)
x + 2y = -6 ...6)
x = -6 - 2y
Putting above value of x in eq 5) , we get :
2( -6 - 2y ) - 3y = 16
-12 - 4y - 3y = 16
7y = -28
y = -4
x = -6 - ( 2× -4 )
x = 2
Hence, this is the required solution.

Answer:
Answer:
r = 6 in
Step-by-step explanation:
The volume of a cylinder of radius r and height or length h is
V = πr²h.
Here, we need to solve for the radius; we get:
V
------------- = r²
πh
904.23 in³
This works out to r² = ----------------- = 35.97 in²
π(8 in)
Finally, take the square root of this result to find the radius, r:
r = √35.97 in² = 6 inches
