David buys a large circular pizza that is divided into eight equal slices. He measures along the outer edge of the crust from one piece and finds it to be 5.5 inches. What is the diameter of the pizza to the nearest inch??
Please help and show work!! Thanks!!!!!!!!!!!

The circumference is eight times the measurement of one piece, so 8 x 5.5 = 44 inches. The diameter is the circumference divided by pi, so 44 divided by 22/7 or 44 x 7/22 = 14 inches.

basically (without blatantly stating the answer), you take the crust length ( 5.5) and multiply it by the number of pieces in the pizza (8), to find the circumference of the pizza...then you divide the circumference by pi (3.14 or whatever they want you to use) to find the diameter (remember C= 2(pi)(r), and 2 times the radius would be the diameter...) hope this helped...

***ok..this very easy
***if he measures from the tip of one piece tho the crust that is the radius(half of the diameter....so the radius is 5.5
***if you draw out a circle and divide it into 2 halve sthe line that cuts them is the diameter.
***now that you have the radius of 5.5 just multiply it by two to get hte diameter....so the diameter in 11 inches

circumference = pi times diameter
c = (pi)(d)
5.5x8=c
44=c
pi= 3.14
44=(pi)(d)
44/pi = d
14 = d
The diameter is 14.
hope this helped
