28.28

Step-by-step explanation:

3.142 × 3 × 3

= 28.28

Step-by-step explanation:

Area of a circle = pie r squared

But we haven't gotten the radius yet so to find radius, we have to divide the diameter by two.

Which is 9 ÷2 = 4.5

So now we have 4.5 as our radius so lets solve for the area now.

Now area = Pie r squared

And pie is 3.142×4.5×4.5

Our final answer becomes 59.38m

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
