Answer:
Perimeter = 21 units
Volume = 110 cubic units
Step-by-step explanation:
Let the center of circle be (x,y).

4x - 18y = - 45

4x + 8y = 4
x + 2y = 1
Solving these 2 equations,
4 - 26y = -45
y = 
x = 
radius = 3.35
Perimeter = 2
= 21 units
Volume of cylinder = 
We have to add the volumes of the cylinders.
Volume of smaller cylinder =
= 8
Volume of larger cylinder = 27 
Total volume = 35
= 110 cubic feet
The first one is A and the second one is C
Answer:
( 3.6 × 10 ^-5 ) ÷ ( 1.8 × 10² ) = 2 × 10^-7
Hello :
f(x) = <span>a(x-k)²+k....... the point vertex is (h , k )
in this exercice : h = -3 and k = -1 s0 f(x) = a(x+3)²-1
find : a
but f(0)=8
a(0+3)² -1 = 8
9a-1=8
9a =9
a=1
f(x) =(x+3)²-1 =x²+6x+9-1
f(x) = x²+6x+8 .... (</span><span>the quadratic function in standard form )</span>
