Find the area of the shape.
stepan [7]

<u>Given</u>:

Given that the radius of the circle is 4 units.

The given figure is \frac{3}{4}th of the circle.

We need to determine the area of the \frac{3}{4}th of the circle.

<u>Area of the circle:</u>

The area of the circle can be determined using the formula,

A=\pi r^2

Substituting r = 4, we have;

A=\pi (4)^2

A=16 \pi

Thus, the area of the circle is 16π units².

<u>Area of the </u>\frac{3}{4}<u>th of the circle:</u>

The area of the \frac{3}{4}th of the circle is given by

A=\frac{3}{4}(16 \pi)

A=12 \pi

Therefore, the area of the shape is 12π units².

THIS IS WORTH 50 POINTS WILL MARK BRAINLYEST PLEASE HELP
zloy xaker [14]
Since the first equation says y= x-4, substitution that for the y value in x + y = 6

x + x - 4 = 6

add up the x’s to get 2x - 4 = 6

add 4 to both sides to get 2x = 10

divide both sides by 2 to get x = 5

the x value is 5

then, to figure out the y value, substitute 5 for the x value in y = 5-4

the y value is 1

final answer: x = 5 and y = 1

hope this helped!!
