3 0

Answer:

The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle you need to go half way around the circle and then across a diagonal to get back to where you started so the perimeter is 1/2 π × d + d.

What is the annual interest rate is 1=$160.67, p=$2000, t=8 months
Sergeeva-Olga [200]
Please use " i " to denote "interest."

the formula for simple interest is i = p r t.

Here, i = $160.67 = $2000 (r) (8/12)


Solving for the interest rate, r = ($169.67)(12/8)/ $2000 = 0.127, or 12.7%
