A 12-inch diameter pizza has 22 calories per square inch.
kipiarov [429]

Answer:

2,486.88\ calories

Step-by-step explanation:

step 1

<u>Find the area of the pizza</u>

The area of a circle is equal to

A=\pi r^{2}

we have

r=12/2=6\ in

substitute

A=(3.14)(6^{2})=113.04\ in^{2}

step 2

we know that

A 12-inch diameter has 22 calories per square inch

By proportion

Find how many calories are in the entire pizza

so

\frac{22}{1}\frac{cal}{\ in^{2}}=\frac{x}{113.04}\frac{cal}{\ in^{2}}\\ \\x=22*113.04\\ \\x=2,486.88\ calories

What is probability?

Probability is the branch of mathematics concerning numerical descriptions of how probably an event is to do, or how likely it's that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.( note 1)( 1)( 2) The advanced the probability of an event, the more likely it's that the event will do. A simple illustration is the tossing of a fair( unprejudiced) coin. Since the coin is fair, the two issues(" heads" and" tails") are both inversely probable; the probability of" heads" equals the probability of" tails"; and since no other issues are possible, the probability of either" heads" or" tails" is1/2( which could also be written as0.5 or 50).

Annalise withdraws $22.50 each day from her account for a week. How can you represent the change in her account after 2 weeks?
nadya68 [22]

Answer: She would have $315

Because there are 7 days in a week so you multiply 22.50 by 7 and you get 157.5, Then because she does it for two weeks you multiply 157.5 by 2 and you get 315

Hope this helps
