d over > 4

In terms of the radius r, the formula for the area A of a circle is:

A = πr²

Since the radius r is one-half the diameter d of a circle, i.e., r = d/2, then substituting into the formula for the area A of a circle, we have:

A = π(d/2)²

A = π(d²/2²) by the "Power of a Quotient" property of exponents, i.e., (a/b)ⁿ = aⁿ/bⁿ, where a and b are real numbers, b ≠ 0, and n is an integer.¹

A = (πd²)/4 is why we may have to divide by 4 when calculating the area of a circle.

Step-by-step explanation:

b

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
