Answer:
x= -4 & y=-12
Step-by-step explanation:
multiply y=3x by 2
giving you 2y=6x
subtracting 2y=x+20 from 2y =6x
=> 5x=-20
dividing through by 5
=> x=-4
put x=-4 into y=3x
=> y=3(-4)
<em>y</em><em>=</em><em>-12</em>
Answer:
V = 825
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The radius is 1/2 d = 1/2 (10) =5
Using 3 for pi
V = 3 ( 5)^2 * 11
V = 825
