Answer 2

Answer:

 $7920 \mathrm{~cm}^2$

Explanation:

Step : 1Radius of the cylindrical penholder's rounded end ,r = 3cm

Size of the pen holder, h = 10.5cm

Surface area of a penholder = CSA of pen holder + Area of base of penholder

$\begin{aligned}& =2 \pi r h+\pi r^2 \\& =\left(2 \times \frac{22}{7} \times 3 \times 10.5\right)+\left(\frac{22}{7} \times 3^2\right) \\& =\frac{1584}{7}\end{aligned}$

Step : 2As a result, the area of one competitor's cardboard sheet is $\frac{1584}{7} \mathrm{~cm}^2$ As a result, 35 contestants used the same area of cardboard sheet $=35 \times \frac{1584}{7}=7920 \mathrm{~cm}^2$

Therefore, $7920 \mathrm{~cm}^2$ For the tournament, a cardboard sheet will be required.

Step : 3Winning a competition triggers your brain's reward regions and releases dopamine (the feel-good hormone) into the hypothalamus, the pleasure centre of the brain. When you feel this thrill, you want to feel it again and again, which leads you to desire to be a part of a competition.
