Answer:

36 π square feet

Step-by-step explanation:

so the formula for area of a circle is πr^2

so the radius is 6, which we can just plug in

π(6)^2

36π

so option 3

What is y = 6/3x - 2 in standard form?

umka2103 [35]

Y = 6/3x - 2
Just move x to the other side,
y - 6/3x = -2
Multiply by -1,
6/3x - y = 2

In short, Your Answer would be 6/3x - y = 2 or 2x - y = 2

Hope this helps!

A home is to be built on a 56 foot 9 inch wide lot. The house is 5 feet 5 inches from the side of the lot and is 34 feet 10 inch

Anni [7]

Check the picture below, so the distance of the house from the other side is that blue gap.

so, there are 12 inches in 1 foot, so let's just convert all those feet to inches and subtract them.

$\bf 56'\implies (56\cdot 12)''\implies 672''
\\\\\\
5'5''\implies (5\cdot 12+5)''\implies 65''
\\\\\\
34'10''\implies (34\cdot 12 + 10)''\implies 418''\\\\
-------------------------------\\\\
672''-(65+418)''\implies 189''\implies 15'9''$

The diameter of a circle has length 12. The center is at*(-5, 2). Give the equation

labwork [276]

Answer:

Equation of the circle is : $x^{2} + 10x + y^{2} -4y -7 =0$

Step-by-step explanation:

Let us consider the image attached in the answer area.

The center O has the co-ordinates i.e. (-5,2) and the diameter given is 12 units.

We know that radius is half of diameter.

$\text{Radius = }\dfrac{\text{Diameter}}{2}$

$\text{Radius = }\dfrac{12}{2}\\\Rightarrow \text{Radius = 6units}$

The equation for circle given the center and radius, can be represented as:

$(x-a)^{2}+ (y-b)^{2} = r^{2}$

Where (a,b) is the co-ordinate of center and r is the radius.

Let us consider the following formula:

$(p+q)^2 = p^{2}+ q^{2} +2pq\\(p-q)^2 = p^{2}+ q^{2} -2pq$

$(x-(-5))^{2}+ (y-2)^{2} = 6^{2}\\\Rightarrow (x+5)^{2}+ (y-2)^{2} = 36\\\Rightarrow x^{2} + 25 + 10x +y^{2} + 4-4y=36\\\Rightarrow x^{2} + 10x +y^{2} -4y-7=0$

Hence, Equation of the circle is : $x^{2} + 10x + y^{2} -4y -7 =0$
