A circle with radius 10 cm is drawn somewhere on a rectangular piece of paper of dimensions `40 cm xx 30 cm.` This paper is kept horizontally on table top and a point is marked on the rectangular paper without seeing towards it. Find the probability that it will marked outside the circle. `("Take "pi=(22)/(7))`

Explanation

To solve the problem, we need to find the probability that a randomly marked point on a rectangular piece of paper will fall outside a circle drawn on it. Here are the steps:

### Step 1: Calculate the area of the rectangle
The dimensions of the rectangle are given as 40 cm by 30 cm.

\[ \text{Area of rectangle} = \text{length} \times \text{width} = 40 \, \text{cm} \times 30 \, \text{cm} = 1200 \, \text{cm}^2 \]
