Determine the equation of the circle graphed below.
myrzilka [38]

Answer:

=  >  {x}^{2}  +  {y}^{2}  + 6x - 14y + 49 = 0

Step-by-step explanation:

From the graph we can see that

Diameter = 6 units

=> Radius = 3 units and centre is at (-3,7)

=> Equation is Circle with centre (-3,7) and radius of 3 units will be

=  >  {(x + 3)}^{2}  +  {(y - 7)}^{2}  =  {3}^{2}

=  > ( {x}^{2}  + 6x + 9) + ( {y}^{2}  - 14y + 49) = 9

=  >  {x}^{2}  +  {y}^{2}  + 6x - 14y + 49 = 0

a cylinder and a cone have the same radius and height. The volume of the cylinder is 534ft3 . what volume of the cone?
DochEvi [55]

Answer: 178 ft^3

Step-by-step explanation:

A cylinder has the formula V=pi radius ^2 height

A cone has the formula V= 1/3 pi radius ^2 height

So 1/3 of the volume of the cylinder is the volume of a cone

1/3 of 534 = 178 ft^3
