Answer:

The volume is 254.34

Step-by-step explanation:

If the cylinder has a diameter of 6 inches, then its radius would be 3 inches.

To know what the height of the cylinder is, the problem tells us that the height is three times the radius. 3 times 3 inches would be 9 inches.

Now we know that

r = 3 inches

h = 9 inches.

The formula to know the volume of a cylinder is:

V = πr²h

V = π(3)²(9)

V = π (9)(9)

V = 81π

V = 81 (3.14)

V = 254.34

Radius is 3 in and height is 9 in. Volume is 3²×9π=81π=254.34 cu in.

When calculating accrued interest over several years that compounds annually, you must _____.

Darina [25.2K]

When calculating accrued interest over several years that compounds annually, you must calculate a new principle each year, adding the accrued interest from the previous year. At the beginning of the new interest period, all the accrued interest is added to the principal which forms a new principle figure that the interest is then counted on.

If a = 12 and 120% of a is equal to 80\% of bthen what is a + b ?

Novosadov [1.4K]

Answer:

The answer is 30

Step-by-step explanation:

First you have to find 120% of a (12).

$\frac{12}{1} \times \frac{120}{100} = 14.4$

Therefore; 14.4 is 80% of b, and we are trying to find 100% of b

$14.4 = 80\% \\ x = 100\%$

we do not know what is 100% therefore we call it *x*. In order to find this unknown value *x* we cross multiply.

$14.4 \times 100\% = 80\% \times x$

This is the same as saying;

$14.4 \times 1 = x \times \frac{4}{5}$

100% percent would be 1 because it is the whole number we are trying to find. The 80% would be 4/5. To get 4/5 you can simply break down 80/100 ( this is 80% as a fraction).

so the new equation is: 14.4= 4/5x

We divide both sides by 4/5. Then we will get x tobe equal to 18. Therefore b is 18. We were asked to find (a + b) so. 18+12 = 30
