Question

A 6 inch personal pizza has 570 calories, with 240 of those from fat. A 16 inch pizza is cut into 8 slices. Estimate the number of calories in one slice of a 16 inch pizza.

Answer 1

Answer:

506.67 calories

Step-by-step explanation:

Given: A 6 inch personal pizza has 570 calories.

To find: The number of calories in one slice of a 16 inch pizza.

Solution: Area of 6 inches pizza is $\pi (3)^{2}=9\pi$

So, $9\pi =570$ calories

In $\pi =\frac{570}{9}$ calories

Now, area of 16 inches pizza $=\pi (8)^{2=64\pi}$

Now 16 inches of pizza is divided into 8 slices, so 8 slices of pizza will have $64\times\frac{570}{9}$ calories.

So, 1 slice

$=\frac{570}{9} \times\frac{64}{8}$

$=\frac{190}{3}\times8$

$=\frac{1520}{3}$

$=506.67$ calories

Hence, 1 slice of 16 inches pizza will have 506.67 calories.
