What is the BEST approximation of the area of the shaded region in the figure below?

B. 48 cm^2

Step-by-step explanation:

The area of a circle is r^2. To find the area of the shaded region find the area of both 5cm and 3cm, both of the circles.

I'll call r = 5 circle a & r = 3 circle b

Circle A area is 78.55 cm^2

Circle B area is 28.278 cm^2

Now minus the area of B from that of A; 78.55 - 28.278 = 50.272

If you don't have a calculator then multiply the radius squared by 3 and if you have time, add a tenth to the total radius and then do the same and then use the process of alimination to remove any answers that seem unlikely and work from there.

A = 75 + 2.5 = 77.5 cm^2

B = 27 + .9 = 27.9 cm^2

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
