Find the area of the circle.

half of 18 is 9

9 squared is 18

18 x 3.14 = 56.52

Step-by-step explanation:

Formula of circle:

radius squared x pie (3.14 or 22/7)

C. 254.34 in^2

Step-by-step explanation:

The formula for area of a circle is πr² (pi x radius x radius).

Here, only the diameter is shown.

To find the radius, divide the diameter by 2.

18 / 2 = 9

9 is the radius.

We use 3.14 as π (pi).

Now we have the final equation.

pi x radius x radius

3.14 x 9 x 9 = 254.34 in^2.

Therefore, the area of the circle is 254.34 in^2.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
