Explanation

Let the circumference of the circle = perimeter of the square = P  

- Circumference of circle = 2πr  

- Perimeter of square = 4a (a = side of square)  

So, 2πr = 4a ⇒ a = (πr)/2

- Area of circle = πr²  

- Area of square = a² = (πr/2)² = (π²r²)/4

Now compare:

πr² (circle) vs. (π²r²)/4 (square)  

Divide both sides:  

(πr²) / ((π²r²)/4) = 4/π > 1 ⇒ area of circle > area of square.

Explanation

 The sensitivity of blood tissue to radiation primarily depends on the mitotic rate of cells.

Cells that divide rapidly, such as blood-forming cells in the bone marrow, are more vulnerable to radiation damage.

This is because radiation mainly affects DNA replication and cell division, making highly mitotic cells more susceptible to its effects
