The world’s largest round pizza was set in december 2012 by five italian chefs. the diameter of this pizza was 131 feet. if this pizza was cut into 50 slices, what would be the area of each slice and the length of the crust for this slice?

First find the area of the whole pizza.

The formula for area of a circle is Area = PI x r^2

The diameter is given as 131 feet, so r would be 131/2 = 65.5 feet.

I will use 3.14 for PI since the problem doesn't say what value to use.

Area = PI x 65.5^2

Area = 3.14 x 4290.25

Area = 13,471.39 square feet

Divide the total area by the number of pieces:

13,471.39 / 50 = 269.43 square feet

To find the length of the crust first find the circumference of the whole pizza:

Circumference = PI x diameter

Circumference = 3.14 x 131 = 411.34 feet

Now divide the total by the number of pieces:

411.34 / 50 = 8.23 feet

Each slice has an area of about 269.43 square feet and a crust length of 8.23 feet.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
