4.What is the area of a circle with a diameter of 5 m?...not urgent

radius=1/2 multiplied by diameter

r=1/2 multiplied by 5

r=2.5

formula=area of circle =pie into r²

22/5 into (2.5)²=area

22/5 multiplied by 6.25=area

22multiplied by 1.25 =area (6.25divided by 5=1.25)

27.5=area of circle

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
