Answer: $A= 32(\pi-2)\ cm^2, \ \ \ P=8\pi\ cm$

Step-by-step explanation:

When we consider Area under arc AC is is representing a quarter as ADBC is a square, $\angle D=90^{\circ}$ .

Area of quadrant = $\dfrac{\pi r^2}{4}$

here r= 8 cm

Area under Arc AC= $\dfrac{\pi (8)^2}{4}=16\pi\ cm^2$

Area of white region ABC = Area of square ADBC - Area under Arc AC

$=8^2-16\pi\ \ [\text{Area of square} = sides^2]\\\\= 64-16\pi\ \ =16(4-\pi)\ cm^2$

Similarly , Area of white region ADC = $16(4-\pi)\ cm^2$

Area of shaded region = Area of square - Area of white region ABC - Area of white region ADC

$=64-(64-16\pi)-(64-16\pi)\\\\= 32\pi-64\ cm^2 \\\\= 32(\pi-2)\ cm^2$

Area of shaded region = $= 32(\pi-2)\ cm^2$

Length of arc AC = $\dfrac{Circumference}{4}=\dfrac{2\pi r}{4}$

$\dfrac{\pi (8)}{2}=4\pi cm$

Perimeter of shaded region = 2(AC) = $8\pi\ cm$

What is the equation that represents the line?

Kryger [21]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 6) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line

m = $\frac{-3+6}{2+2}$ = $\frac{3}{4}$ , thus

y = $\frac{3}{4}$ x + c ← is the partial equation

To find c substitute either ot the 2 points into the partial equation

Using (2, - 3), then

- 3 = $\frac{3}{2}$ + c ⇒ c = - 3 - $\frac{3}{2}$ = - $\frac{9}{2}$

y = $\frac{3}{4}$ x - $\frac{9}{2}$ ← equation of line
