An artist is creating a stained glass design. She uses a lead border around each piece. The radius of the circle is 2 ¼ in. Use pi π = 22/7 a. The diameter of the circle measures inches.

b . The diameter of the circle is the same length as one of the square.

c. Find the perimeter of the square.
P = 4 x =

d. Find the perimeter of the circle.
C ≃ 22 x ≃
7

e. Find the area of the circle.

The correct answer is -

a. 4.5 inches.

b. side or arm (a)

c. (a) or 4.5, and 18

d. (d) 4.5, and 14.1428

e. 22/7 × r^2 = 15.90

Step-by-step explanation:

Given :

Radius or r = 2 ¼ inches

Solution:

a. the diameter of the circle -

d = 2r

= 2 ¼  *2

= 2.25*2

= 4.5

b. The diameter of the circle is the same length as one side or arm of the square which is

a = d = 4.5

c. The perimeter of the square

P = 4a = 4d = 4*4.5 = 18

d. Perimeter of the circle =

2πr = πd = (22/7)*4.5

= 14.1428

e. the area of the circle =

22/7 × r^2

= 15.90

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
