Step-by-step explanation:

The formula for the area of a circle: $A=\pi r^{2}$

Given:

Radius = 8 cm

Substitute 8 for r (radius):

$A=\pi 8^{2}$

Solve:

$A=\pi (64)$

$A=64\pi$ $or$ $201.062 cm^{2}$ $rounded.$

If every day I make 2 dollars and every time I reach 50 dollars it adds 25 cents to my daily income how many days will it take f

Answer:

659

Step-by-step explanation:

We assume the daily rate increases at each multiple of $50. When the balance reaches $50 on day 25, the pay on day 26 is $2.25.

Similarly, when the balance reaches 9628.75 on day 658, the pay will be $50 on day 659.

I found this easiest to solve using a computer program. A spreadsheet can do it by computing the number of days between raises. This is shown in the attachment.
