Answer:

given ,

radius of circle = 7 inches.

( value of pi = 22/7 )

to calculate - circumference of the circle.

$circumference = 2\pi \: r \\ \\ \dashrightarrow 2 \times \frac{22}{\cancel7} \times \cancel7 \\ \\ \dashrightarrow \: 2 \times 22 \\ \\ \dashrightarrow44 \: inches {}^{2}$

hope helpful :D

A flight averages 460 mph. The return flight averages 500 mph due to tailwind. The total flying time is 4.8 hours how long is ea

Nesterboy [21]

We know that time is distance over velocity, that is:

time = distance / velocity

t = d / v

Now from the given:

d / 460 + d / 500 = 4.8

Now we can find for d:

d = 4.8 / [1/460 + 1/500]

d = 1150 miles

So the time of each flight is:

flight = 1150 / 460 = 2.5 hours

<span>return flight = 1150 / 500 = 2.3 hours</span>

-. A businessman plans to retire in 30 years. As part of his retirement plan, he has

stepladder [879]

Answer:

A = $45948

Step-by-step explanation:

Given the following data;

Principal = $8000

Interest rate = 6% = 6/100 = 0.06

Time = 30 years

To find the future value, we would use the compound interest formula;

$A = P(1 + \frac{r}{100})^{t}$

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

t is the number of years for the compound interest.

Substituting into the equation, we have;

$A = 8000(1 + \frac{6}{100})^{30}$

$A = 8000(1 + 0.06)^{30}$

$A = 8000(1.06)^{30}$

$A = 8000(5.7435)$

A = $45948
