FIRST RIGHT ANSWER GETS BRAINIEST
What is the area of the gray region, in square units, if the radius of the larger circle is four times the radius of the smaller circle and the diameter of the smaller circle is 2 units? Express your answer in terms of pi

OK, no figure, but from the comment is sounds like the grey area is the big circle minus the small circle.

The diameter of the small circle is 2 so its radius is 1 and its area πr² is π.

The radius of the larger circle is 4, so area 16π

The shaded area is 16π - π

15π

the answer for this question is 38

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
