The answer will be C.13.85. A=πr^2, so A=π2.1^2≈13.85. As a result, the area of the circle is about 13.85. Okay, π=3.14, and r^2=2.1×2.1=4.41. Then, 4.41×3.14≈13.85 to find the area of this circle. Hope it help!

If you want to use integer tiles to find the product of 2(-5), think of it as you having 2 groups of 5 negative tiles, that is

-1 -1

-1 -1

-1 -1

-1 -1

-1 -1

Think of it as you having each of the -1 inside it's distinct tile. Now adding up these tiles you have -10.

Therefore 2(-5) is -10 using integer tiles.

If we are to use the number line, first draw your number line, then think of it as jumping twice while each jump is -5 big.

So the first jump from 0 will land on -5 and the second jump will land on -10 and that is the required answer using the number line.
