Answer:
6cm
Step-by-step explanation:
The radius is half of the diameter. Being 12 inches, the radius will be 6 inches.
Answer:
Step-by-step explanation:
Distribute:
Y+-3+(-2)(x)+(-2)(1)
Y+-3+-2x+-2
Combine like terms
Y+-3+-2×+2
(-2×)+(y)+(-3+-2)
-2x+y+-5
Answer: We know that for any circle with radius r the formula for the area and circumference of the circle is given as: Area of circle=πr². ... Hence, to describe the relationship between the area of a circle and its circumference. The Area of circle is 1/2 times the radius times the circumference.
Step-by-step explanation:
What is the Pythagorean Theorem?
The PyTheorem states that -- actually, why not just simplify things and make it a formula?
where a and b are legs of a triangle and c is the hypotenuse of a triangle.
It is only true applying to right triangles.
Now what are the legs of a triangle?
The sides that are NOT opposite the 90 degree angle!
Now, all you have to do is find the LENGTHS of the three triangles!
Rise over run, remember?
Let's take the triangle in the top right of the coordinate plane for example.
A=(1,1)
B=(4,4)
unnamed point=(4,1)
Rise, or length of unnamed point to B?
(4,1) to (4,4)
(x,y), remember!
So? 4-1=3!
Run, or length of unnamed point to A?
(1,1) to (4,1)
Remember (x,y)?
So, 4-1=3!
The triangle has legs of 3 and 3.
Square em and add!
9+9=18
That's for length of AB!!
Now do the same for the remaining lengths!
Hope this helps!
