The threat from acid deposition has been steadily increasing in the 21st century because of the increase in the number of industries during this period. The acid particles get trapped in the atmosphere and falls as raid on earth. These acid particles are increasing with the booming of the industrial sector.
Perimeter = 3x. Area = x^2 * sqrt(3)/4. Explanation of area:. You can divide an equilateral triangle into 2 right triangles, each with a common side we will call y.. Area = area of first right triangle + area of second right triangle = (x/2)*y/2 + (x/2)*y/2 = xy/2. Now: y^2 + (x/2)^2 = x^2 so y…
The circle with diameter of 24 means that 2

r = 24.
Solving for r, we get

r=24.
Dividing both sides by

, we get r=24/

.
The area of the full circle is

times 24 squared over

. The

being multiplied cancels out, meaning that 24 squared over

is the area of the full circle. 24 squared is 576, and dividing by 16 we get

as the answer.
