If a circle has center (a,b) and radius r, the equation is

So, you have

Answer:
Surface area of the cube =
Step-by-step explanation:
Given shape in figure 1:
Cube with edge length = 5 cm
To find the surface area of the cube.
Solution:
The surface area of a cube is given by the formula:

where
represents the length of the edges of the cube.
For the given cube 
Plugging
in the formula to find the surface area of the cube.

∴ 
Each equation form a straight slanting line. For the first equation, it is slanting towards the right which denotes that it has a positive slope. For the the second equation, its plot is slanting towards the left denoting that its slope is negative. Common to both equation is the point (-1.25, 2.75). At this point, the two lines intersect.
Answer:
8
Step-by-step explanation:
Since the entire triangle was translated, each point gets shifted 9 left and 3 up which does not alter the triangle measurements, so all sides and angles of triangle' is the same as the original.
