Answer:

A = P (1 + i)^n      A is the final amount

                            P is the initial amount

                            i = interest / period

                            n = number of periods

A = 315 * (1 + .015)^1.5 = 322.11

Plz help!! Will give 30 points!!
Inessa [10]

Answer:

B) 12

Step-by-step explanation:

C is the circumference, d is the diameter, and r is the radius.  They are related by the following equations:

d = 2r

C = πd = 2πr

If d = 6.0, then r = 3.0.

If C / C' = 0.25, then:

(2πr) / (2πr') = 0.25

r / r' = 0.25

3 / r' = 0.25

r' = 12
