6. Kriti has a circular swimming pool in her house. The radius of the swimming
Evgen [1.6K]

Answer:

Total walk she did around the pool every morning = 141.3

Step-by-step explanation:

Given - Kriti has a circular swimming pool in her house. The radius of the swimming  pool is 22.5 cm. She walks one round every morning before diving in the pool.

To find - How far does she walk around the pool every morning?

Proof -

Given that, the swimming pool is circular in shape.

So,

1 round of circle = Circumference of circle.

As we know that,

Circumference = 2\pi r

                         = 2*\pi *22.5

                         = 141.3

∴ we get

Total walk she did around the pool every morning = 141.3

<h3>to understand this</h3><h3>you need to know about: </h3>
  • algebra
<h3>let's solve:</h3>
  1. \sf rewrite \: 105 \: as \: 100 + 5 :  \\  \sf (100 + 5 {)}^{2}
  2. \sf use \: (a + b {)}^{2}  =  {a}^{2}  + 2ab +  {b}^{2} \:  to \: simplify :  \\  \sf  {100}^{2}  + 2.100.5 +  {5}^{2}
