Place the circles in order from the circle with the smallest area to the circle with the largest area.

4th,  3rd, 1st,  2nd.

Step-by-step explanation:

Comparing the radii will give the same result as comparing the areas because the areas are directly proportional to the square of the radii (that is Area = pi r^2).

The second circle has a radius of 27 units.

The 4th circle has a radius of 19/2 = 9.5 units.

The third circle  radius is worked out below:

2 pi r = 87.92 so r = 87.92 / 2 pi =  13.99 units.

The first one has radius = √ (1040.09 / pi ) = 18.2 units.

I did it this way because it was less calculation!

Step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

35 is an outlier
