Determine the value of pie for a circle with a diameter of 9 inches and a circumference of 28.26 inches
jarptica [38.1K]

Hello from MrBillDoesMath!

Answer:

3.14

Discussion:

C = circumference, r = radius, d = diameter = 2 r

For a circle, C = 2 Pi r  = d Pi

Substituting the values in the question gives


C = d Pi

28.26 = 9 Pi       => divide both sides by 9

Pi = 28.26/9  = 3.14


Thank you,

11. The length of a rectangle is three times its width. The perimeter of the
Elenna [48]

Answer: The length of the rectangle is 37.5 inches and the width is 12.5 inches

Step-by-step explanation: The dimensions of the rectangle is not given but we have clues given. The length is given as three times it’s width which means if the width is W, then the length would be given as 3W (three times the width). Also the perimeter is given as 100 inches and the formula for the perimeter is;

Perimeter = 2(L + W)

We can now insert the known values as follows;

100 = 2(3W + W)

100 = 2(4W)

100 = 8W

Divide both sides of the equation by 8

12.5 = W

Having calculated the width as 12.5 inches, the length now becomes

L = 3W

L = 3 x 12.5

L = 37.5

Hence the length is 37.5 inches and the width is 12.5 inches
