Answer:

Circumference = 2 pi r = 2*3.14 *r = 20

radius r = 20 / 2*314 = 3.185

Area = pi r^2 = 3.14 * 3.185^2 = 32 m^2 to nearest whole number

Your friend borrows $100 from you and promises to pay you back $109 in 8 months. What annual percentage rate (A.P.R.) are you ch

Answer:

$12.0\%=0.12$

Step-by-step explanation:

We have been given that your friend borrows $100 from you and promises to pay you back $109 in 8 months.

We will use simple interest formula to solve our given problem.

$A=P(1+rt)$ , where,

A = Amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

Convert 8 months to year:

$\frac{8}{12}\text{ year}=\frac{2}{3}\text{ year}$

$108=100(1+r*\frac{2}{3})$

$108=100+r*\frac{2}{3}\times 100$

$108-100+r*\frac{200}{3}$

$108-100=100-100+r*\frac{200}{3}$

$8=r*\frac{200}{3}$

$8\times \frac{3}{200}=r*\frac{200}{3}\times \frac{3}{200}$

$\frac{24}{200}=r$

$r=\frac{24}{200}$

$r=0.12$

Convert to percent:

$0.12\times 100\%=12\%$

Therefore, you are charging 12% APR to you friend.

If the arrow is pointing downwards, it means it is negative (like the one in your picture). If the arrow points upwards, it is positive!! :)
