an equation for a circle has formula
(x-m)² + (y-n)² = r²
where (m,n) is its center
and r is its radius
so, the equation has center (4,3) and radius 4
the equation is derived from the pythagorean theorem
Answer:
X= -50
Step-by-step explanation:
Remove the parenthesis
multiply both sides by two
x - 6 = -56
Move the 6 to the other side
x = -56 + 6
x = -50
1/4+ (-3/4) = -0.5
-4 1/2 +2= -2.5
-8+ (-11/8)= -9.125
The volume of a sphere with radius 
is 
. If the radius is multiplied by a constant 
, then the new volume is 
, which is equal to 
. This means that the volume of the sphere is multiplied by 
.
a. If the radius is doubled, the volume is multiplied by 8
b. If the radius is tripled, the volume is multiplied by 27
c. if the radius is quadrupled, the volume is multiplied by 64
