Find the exact area of a circle having the given circumference.

Answer:

(9/4)π

Step-by-step explanation:

I will assume that the given circumference is 3π (I do not recognize your 'A').

The formula for the circumference of a circle of radius r is C = 2πr.  This equals 3π.  Thus, 2r must equal 3 and so r equals 3/2.

The exact area of this circle is A = πr² = π(3/2)² = (9/4)π

Suppose that you begin saving up to buy a car by depositing a certain amount at the end of each month in a savings account which
SpyIntel [72]

Answer:

$2,221.6 monthly

Step-by-step explanation:

A = P(1 + r)^n

A is the total amount I intend to save = $15,000

r is the yearly interest rate = 3.6% = 0.036

n is the duration to achieve my goal = 4 and 1/2 years = 54 months

15,000 = P(1 + 0.036)^54

15,000 = P(1.036)^54

P = 15,000/6.752 = 2,221.6

I need to put $2,221.6 into the savings account monthly
