Not getting any of this

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

4,3,1

Step-by-step explanation:

2^a3^b5^c=2160

2^a3^b5^c=2^4 3^3 5^1

a=4,b=3 and c=1
