Population growth is generally given by an exponential function,
<em>f</em>(<em>x</em>) = <em>a</em>*<em>b</em>^<em>x</em>, where <em>a</em> is the original population, <em>b</em> = 1 + the rate of growth (written as a decimal number), and <em>x</em> is the amount of time. In our case we have
<em>p</em>(1 + 0.065)<em>^</em>1<em>
</em>= <em>p</em>(1.065) = 1.065<em>p</em>
Calculate the circumference and then add the 1 cm overlap:
C = pi*(6.6 cm) + 1 cm = 21.7 cm.
Next, mult this C by the height, 8.8 cm: Total area is 21.7 cm times 8.8 cm,
or 191.3 cm^3 (answer)
Answer:
The closest answer is $30.00, the original answer is $29.99
He would have 4 quarters and 7 dimes. The reason is because 1 quarter is 25 cents. And a dime is 10 cents. Add it together and you would get $1.70. Hope this helps! Have a great day :)
