Answer:

see the explanation
Step-by-step explanation:
we know that
The area of the base of a cylinder is given by the formula

where
r is the radius of the circular base
If the radius is doubled
then

The new base area is


so

therefore
The new area of the base is 4 times the area of the original base
Answer:
You would move 10 units to the right from zero on the x-axis.
The cost of the metals from the calculations performed is $ 402421.
<h3>What is density?</h3>
Density can be explained as a quantity having mass per unit volume and this can be calculated as:
Mass of the metal = ?
Density of the metal = 7.3 g/cm^3
height of the metal = 610 cm
radius of the metal = 8.7 cm
Volume of a cylinder can be calculated by using the formular below:
And this can be used by inserting the given values which is

Then we can calculate the mass as :
Mass = (density * volume)

=Since the cost is $0.38 per kilogram, then 3657 Kg costs
;( 1059003kg * $0.38)
= $ 402421

Answer:
No.
Step-by-step explanation:
Substitute in the coordinate (0, 0) and the resultant expression is:
0 > 2(0) + 3
0 > 3
We know that this is false, so it is not a solution to that inequality.
To make it simpler you could take away the plus sign and just make it 7 - 4.
the answer would be 3.
