Given parameters:
Charge per month = $65
Percentage on rent= 6%
Amount paid by Jack per month = $164
Unknown:
Monthly rent on his property = ?
Solution:
Monthly rent on his property can be found by;
Amount paid by Jack per month = Charge per month + 6% of monthly rent
Let the monthly rent = x ;
So;
164 = 65 + x
164 - 65 =
99 =
6x = 9900
x = 1650
Monthly rent on his property is $1650
We are given Volume of the larger cylinder is = 1600 cubic centimeters.
Height of the larger cylinder = 16 cm.
We know formula of volume of a cylinder V=, where r is the radius of cylinder, h is the height of the cylinder.
Plugging value of V and h of larger cylinder, we get
Dividing both sides by 16, we get
Taking square root on both sides, we get
r=10.
Therefore, radius of the larger cylinder is 10 cm.
We are given cylinders are similar .
<u>Note: The radii and heights of similiar cylinders are in same ratio.</u>
Therefore, we can setup a proportion:
Let us take radius of small cylinder is x.
Multiplying both sides by 10, we get
x=2.50.
Therefore, radius of the small cylinder = 2.5 cm.
Now, plugging radius =2.5 and height = 4 in the formula of volume the cylinder, we get
Therefore, correct option is 25 pi cm^3.
