A pizza with radius 7 in. is cut into 12 equal-sized pieces. What is the area of each piece? Round to the nearest hundredth of an inch.

12.83 inch^2

Step-by-step explanation:

To calculate the area of each piece, we need to first need to calculate the area of the pizza as a whole.

Mathematically the area A of the pizza can be calculated using the formula;

A = π * r^2

where our r here is 7 in

Thus, A = 22/7 * 7 * 7 = 154 inch^2

The area of each piece of the pizza is thus 154/12 = 12.8333333 inch^2

To the nearest hundredth, this is 12.83 inch^2

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
