the volume of a cone is 36π cubic units. What is the volume of a cylinder that has the same base area and the same height?

1 answer:

6 0

V_cone = 1/3 pi * r^2 * h
V_cylinder = pi*r^2*h

If you multiply the cone's volume by 3 then you get the cylinder's volume. They become the same formula
3 V_cone = pi r^2 h
Since the cone's volume is 36pi They cylinder's volume is 3*36pi = 108 pi

Ralph Phillips obtained a 12 month, $1500.00 loan at 12%. His monthly payment is $135.20. For the first payment find:

Vika [28.1K]

Answer:

a. The interest is US$ 8.20

b. The payment to principal is US$ 125.

c. The new balance is: US$ 1,465.20 (including principal and interest) or US$ 1,375 (just the principal).

Step-by-step explanation:

1. Let's review the information given to answer this question correctly:

Loan obtained by Ralph Phillips = US$ 1,500

Time of paying back the loan = 12 months

Interest rate of the loan = 12%

Monthly payment = US$ 133.20

2. Let's find a, b and c.

The principal is US$ 1,500. Dividing it by 12 months, the monthly payment of principal is US$ 125. Therefore,

a. The interest is (133.20 - 125) = US$ 8.20

b. The payment to principal is US$ 125.

c. The new balance is: US$ 1,465.20 (including principal and interest) or US$ 1,375 (just the principal).

In designing an experiment involving a treatment applied to 4 test subjects, researchers plan to use a simple random sample of 4

avanturin [10]

There are 48 available subjects. Researchers should select 4 of them for their experiment.
We should find the number of possible different random samples. The order of the selected subjects is not important. This means that we need to find how many different combinations of subjects from total 48 are possible. A formula for the number of possible combinations of r objects from a set of n objects is: n!/r!(n-r)!. In our case n=48 and r=4:
C=48!/44!*4!=48*47*46*45*44!/44!*4!=48*47*46*45/4*3*2*1=4669920/24=
194580.

40% means "40 out of 100"

40 ÷ 100 = 0.40

So, 40% = 0.40 as a decimal
