Answer:

A = 64 pi inches ^2

Step-by-step explanation:

Circumference is equal to

C =2*pi*r where r is the radius

16 pi = 2 * pi *r

Divide each side by 2 pi

16pi/2pi = 2pir/2pi

8 = r

The radius is 8

To find the area, we use

A = pi r^2

=pi (8)^2

= 64 pi

22. I = Prt; P What do I first? It says to solve the equation for the given variable.

LuckyWell [14K]

the first thing you need to do is

divide the whole equation by rt as shown below

$\frac{i}{rt} = \frac{prt}{rt}$

then you cancel out. leaving

$\frac{i}{rt} = p$

which is the same as

$p = \frac{i}{rt}$

X + 3/2 = 3/4 (x - 1/2)

Iteru [2.4K]

this would be your answer, x = 1 - 15/2.

Thanks,
