Answer:

Step-by-step explanation:

2x-4y=-14

Here, we have to form 2x + 4y = 14 as per y = mx + c. Hence the slope = - 1/2 and y-intercept = 7/2

An equation of the form

y = m x + b where

m is the slope and b is the y-intercept.

(-8x+4y=-4) /4

m = 2

Find the area of the shape.

stepan [7]

Given:

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.

Area of the circle:

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.

Area of the $\frac{3}{4}$ th of the circle:

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.
