Answer:

The correct option is B.

Step-by-step explanation:

It is given that the circumference of a circle is 7π units.

The circumference of the circle is

$S=2\pi r$

$7\pi =2\pi r$

$7=2r$

$r=3.5$

The area of the circle is

$A=\pi r^2$

$A=\pi (3.5)^2$

$A=12.25\pi$

The area of circle is 12.25π square unit.

Therefore the correct option is B.

19. A quadratic equation is shown below.

victus00 [196]

Answer:

$\{\sqrt b, -\sqrt b\}$

Step-by-step explanation:

Given

$a^2 - b = 0$

Required

Determine the solution

Since b is a perfect square, the equation can be expressed as:

$a^2 - (\sqrt b)^2 = 0$

Apply difference of two squares:

$(a - \sqrt b)(a + \sqrt b) = 0$

Split:

$(a - \sqrt b)= 0 \ or\ (a + \sqrt b) = 0$

Remove brackets:

$a - \sqrt b= 0 \ or\ a + \sqrt b = 0$

Make a the subject in both equations

$a =\sqrt b \ or\ a =-\sqrt b$

The solution can be represented as:

$\{\sqrt b, -\sqrt b\}$
