Answer:
Radius = 12 cm
Step-by-step explanation:
Given:
Volume of the cylinder is, 
cm³
Height of the cylinder, 
cm
Let the radius be 
Using the formula for volume of cylinder,
Plug in 3165.12 for 
, 7 for 
and solve for .
Therefore, the radius of the cylinder is nearly 12 cm.
Answer:
g(x) = f(x) + 2
Step-by-step explanation:
To move the two to the other side of the equation, you have to add the two to both sides of the equation. The 2 cancels out on the g(x) side, and a 2 is added to the f(x) side.
Answer:
-1.75 I apologize if that is not right but i am 99% sure
Step-by-step explanation:
When you add like terms on the right side you end up with 2x, then all you di is divide both sides by 2 and you end up with -1.75
Answer:
137.5 in^2
Step-by-step explanation:
So, this is basically a rectangle and two right-sides triangles.
First the rectangle: Formula is A=wl
Replace the Values: A = 14*7 98 in^2
Then we solve for the two right-sides triangles.
A= 1
/2a
h=
1
/4
b
^2
sin
(2
θ
)
Top trinangle= A = 25.5 in^2 (height 7 in base 7 in)
Bottom Trinagle A = 14 in^2 (height 7 in base 4 in)
Add results:
98+25.5+14 = 137.5 in^2
