12. Determine the area of the shaded region. 12 in 12 in

Step-by-step explanation:

We know that:

Solution:

Step-by-step explanation:

Area of shaded region = Area of square - area of sphere (4 circles)

here ,

Area of square = ( length)^2

= (12)^2

= 12*12

= 144 sq.in

also,

diametre of circle = 12/2=6 inch

Now,

area of circle = pie d

= 22/7*6

18.857 sq.inch

Area of 4 circles = 4 * area of circle

= 4 * 18.857

= 75.428 sq. inches

Area of shaded region = Area of square - area of

(4 circles)

= 144 sq.inches - 75.428 sq.inches

= 68.571 sq.inches

Therefore , the area of shaded region = 68.571 sq.inches

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
