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

ratio is 2 : 9

the answer is three

13.5 : 3

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
