Answer:
254.47
Step-by-step explanation:
A=πr2=π·92≈254.469
Step-by-step explanation:
1.) Firstly, you need to count out how many things there are. 4 app, 5 entrees, 2 desserts. This makes 11 different things
2.) for 11 numbers there can be 9 ways for each number for 1st nine places since 0 can't be the fist figure and next two are reciprocated from 10 numbers. Therefore 10!/2!
3.)So 99 combinations have 10!/2! Permutations hence total ways are 99*10!/2!
Answer:
You could arrange them 3 different ways <em>at once</em>.
Step-by-step explanation:
You have 12 different cars, but only 4 can be shown at once.
Divide 12 by 4, and you'll get 3.
Therefore, if you wanted to show them all at once, you could make 3 different displays.
