What is the area of a circle with a diameter of 4x - 24? specifically what steps would you take?

answer:

12.56x^2+452.16

step-by-step explanation:

a=pie r^2

(4x-24)/2= 2x-12 which is your radius

(2x-12)^2=4x^2+144

pie=3.14ish

3.14(4x^2+144)

12.56x^2+452.16

answer:

step-by-step explanation:

the formula for the area of a circle is

a = πr².   we need the radius, r, to calculate the circle.

if the diameter of the circle is 4x - 24, then the radius is half that, or

2x - 12.

then the area of the circle in question is   a = πr², or

a = π(2x -12)²

if desired, this could be expanded:

a = π(4)(x - 6)² = 4π(x^2 -12x + 36)

answer: im pretty sure its .8%

step-by-step explanation:

because you move the decimal forward two spaces .

answer:

x intercept is -7 and y intercept is 7.

step-by-step explanation:

in order to find   x intercept of an equation ,we put y =0

and for y intercept we put x =0

therefore y intercept of given equation   y = x+7 is

  plugging   x =0   in the equation ,we get

        y = 0 +7 = 7

        y = 7 ,y intercept is 7

for x intercept ,we plug y =0

        0 = x+7

          x = -7

      so x intercept is   -7

and y intercept is 7
