the number 3.14 is a rounded value of the mathematical quantity pi. if you replace 3.14 with pi, what is the exact formula of rn the circumference in terms of the diameter ,d, in the terms of radius, r?

rectangle that is ther answer you

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

y=1/4x-4
