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:

the answer is (-4,-4)

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
