Area of a circle is found using the formula: A = PI x r^2 where r is the radius of the circle, which is half the diameter.

Using the information in the problem you have:

A= PI x 15^2

A = PI x 225

A = 706.5 sq. In.

Answer:

A =706.5 in^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

We are given the diameter

r = d/2 = 30/2 = 15

A = pi * 15^2

A = pi*225

We can approximate pi by 3.14

A = (3.14)*225

A =706.5 in^2

The square root of a negative number, such as StartRoot negative 144 EndRoot, is undefined. Explain why the square root of –x, S

IRINA_888 [86]

Answer:

see the explanation

Step-by-step explanation:

we have

$f(x)=\sqrt{-x}$

we know that

The radicand of the function cannot be a negative number

$-x\geq 0$

Solve for x

Multiply by -1 both sides

$x\leq 0$

The domain of the function f(x) is the interval -----> (-∞, 0]

The domain is all real numbers less than or equal to zero

The range of the function f(x) is the interval ----> [0,∞)

The range is all real numbers greater than or equal to zero

<em>Example</em>

For x=144

$144\leq 0$ ----> is not true

This value of x not satisfy the domain

substitute

$f(x)=\sqrt{-144}$ ----> this value is undefined

For x=-144

$-144\leq 0$ ----> is true

This value of x satisfy the domain

substitute

$f(x)=\sqrt{-(-144)}$

$f(x)=\sqrt{144}$ ----> this value is defined

therefore

The function will be undefined for all those values of x that do not belong to the interval of the domain of the function
