Answer:

V =9.42 in^3

Step-by-step explanation:

The diameter is 3 inches

The radius is d/2 = 3/2 inches

The volume is

V = 4/3 pi r^2

V = 4/3 ( 3.14) ( 3/2) ^2

V =9.42 in^3

Alexandra [31]

Answer:

102.6666... feet in one second 1232 feet in twelve seconds.

Step-by-step explanation:

Most clear way of solving this breakdown the proportions by keep the value.

1 mile = 5280 feet.

1 hour = 60 minutes = 3600 seconds -- See now it is easy.

Feet per second...

= feet/seconds

(70*5280) = 369,600/3,600 = 102.666666667 -- That is 102.66...feet per second.

For twelve seconds just multiply by 12.

102.666666667*12 = 1232 feet in twelve seconds.

Find the number of years it would take for $1200 to earn simple interest of $324 at an annual interest rate of 6% per year

topjm [15]

ANSWER

It would take 45 good years

<u>EXPLANATION</u>

We calculate simple interest using the formula,

$I=\frac{P\times T\times R}{100}$

From the question,

$I=324$ dollars

$R=6$ %

and

$P=120$ dollars

We substitute into the above formula

$324=\frac{120\times T\times 6}{100}$

$324=\frac{720\times T}{100}$

$324\times100=720\times T$

$\frac{324\times100}{720}=T$

$\frac{324\times10}{72}=T$

$45=T$

Therefore it would take 45 years.
