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:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
