Explanation

In the Tree of Rumour problem, one person passes the rumour to 2 other people every 5 minutes.

Therefore, the total number of people triples every 5 minutes.

0 minutes → 1 person

5 minutes → 3 persons

10 minutes → 9 persons

15 minutes → 27 persons

20 minutes → 81 persons

Using the formula:

3^20/5 =3^4 =81

Explanation

Every year population increase = 700

after five year population increase = 5 x 700= 3500

So intial population = 25000-3500=21500

Explanation

Let's calculate the population after 2 years:

Year 1:

Population = 50,000 + (4% of 50,000)

= 50,000 + 0.04 * 50,000

= 50,000 + 2,000

= 52,000

Year 2:

Population = 52,000 + (4% of 52,000)

= 52,000 + 0.04 * 52,000

= 52,000 + 2,080

= 54,080

The population after 2 years will be 54,080.

Explanation

Let's consider the radius is r and therefore the Area will be πr².

Now the radius is increased by 4 times than the Area would be.

π(4r)² or the area would work to 16 times (4²=16).

Explanation

Formula:

A=pi r^2

Solution:

• Radius = 1 cm

• Area = π × 1²

• Area = 3.14 cm²
