(4x-24)/2= 2x-12 which is your radius
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%
because you move the decimal forward two spaces .
x intercept is -7 and y intercept is 7.
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
