$A=25,000(1+\frac{.062}{4})^{(4)t}$

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

$A=P(1+\frac{r}{n} )^{nt}$

P = initial balance

r = interest rate

n = number of times compounded annually

t = time

Since the balance is compounded quarterly, the number will be used for n.

Now lets plug in the values into the equation:

$A=25,000(1+\frac{.062}{4})^{(4)t}$

(1) the diameter is 20 inches whats the radius? And whats the circumference?

Radius is half the diameter, 10 inches

Circumference is pi times the radius, 10π inches

I won't bother with the approximation, though this one is easy, 31.4159 inches. I'll leave the rest of the calculator work to you if necessary.

(2) the diameter 11 inches whats the radius? And whats the circumference?

Radius half, 5.5 inches. Circ: 5.5π inches

(3) the diameter 3.5 inches whats the radius? And whats the circumference?

Radius, 1.75 inches. Circ: 1.75π inches
