Answer:
(81 pi)/4 or approximately = 63.62 ft^2
Step-by-step explanation:
As it is a circle, the area for a circle is pi*radius^2, where the radius is 4.5 ft, so area = 4.5^2 * pi.

Answer:
financial equations use the formula

where
A is accrued amount
P = principal
r= interest rate
t = number of periods (NOTE: NOT NUMBER OF YEARS !!!)
r = interest rate (NOTE: APR the whole years interest NOT the period)
So in your question the compounding is being done "Semi-annually:
NOTE:
Annual = 1
semi-annual = 2
Quarterly = 4
monthly = 12
So your number of periods is ..... number of years (9) times the number of periods in a year (2 - for semi-annual)
9 * 2 = 18 there are 18 periods

Answer:
p = 15.999999999996
Step-by-step explanation:
Here we have:
22÷16.5 = 1,333333333333
32÷24 = 1.333333333333
since the two triangles are similar then

then
p = 1.333333333333×12
= 15.999999999996
