Answer:

step 1. The circumference (c) of a circle is equal to the diameter of a circle x pi. c = d(pi) = 5pi

step 2. c = 5pi = 5(22/7) = 110/7 = 15 5/7.

Answer:

4\sqrt{37} units is the perimeter of square ABCD.

Step-by-step explanation:

Coordinates of square ABCD:

A = (3,4), B = (2,-2), C = (-4-1) , D = (-3,5)

Distance formula: (x_1,y_1),(x_2,y_2)

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Distance of AB: A = (3,4), B = (2,-2)

AB=\sqrt{(2-3)^2+(-2-4)^2}

AB=\sqrt{(-1)^2+(-6)^2}=\sqrt{37} units

Given that the ABCD is square, then:

AB = BC = CD = DA

Perimeter of the square ABC = AB +BC + CD + DA

AB+ AB+ AB+ AB= 4AB=4\sqrt{37} units

4\sqrt{37} units is the perimeter of square ABCD.
