Find the area of a circle with a diameter of 16.

mylen [45]

Answer:

A = 64 pi

or approximately 200.96

Step-by-step explanation:

The diameter is twice the radius

d = 2r

16 = 2r

Divide by 2

16/2 = 2r/2

8 =r

The area of a circle is

A = pi *r^2

A = pi*(8)^2

= pi *64

Or if we approximate pi as 3.14

A = (3.14) * (64)

A = 200.96

Match the following items by evaluating the expression for x = -6.

Kryger [21]

Step-by-step explanation:

Put the value of x = -6 to all expressions:

$x^{-2}=(-6)^{-2}=\dfrac{1}{(-6)^2}=\dfrac{1}{6}\qquad\text{used}\ a^{-n}=\dfrac{1}{a^n}\\=====================\\x^{-1}=(-6)^{-1}=\dfrac{1}{(-6)^1}=-\dfrac{1}{6}\\=====================\\x^0=(-6)^0=1\qquad a^0=1\ \text{for all real numbers except 0}\\=====================\\x^1=(-6)^1=-6\qquad a^1=a\ \text{for all real numbers}\\=====================\\x^2=(-6)^2=36$
