Which old sensation the writer is talking about?​

Answer 1

Answer:

To find :-

Circumference of the circular swimming pool.

Given :-

Diameter of the circular swimming pool = 42 meters

How can we find the αnswer :-

Here we have diameter of the circular swimming pool firstly we will convert diameter of the circular swimming pool to radius of the circular swimming pool and the by using the formula .

Let's do

\boxed{\red{\:\mathsf{Radius \:=\:\dfrac{Diameter}{2}}}}

Radius=

2

Diameter

Radius = 42/2

Radius = 21 meters

Finding circumference of the circular swimming pool :-

\longmapsto\mathsf{Circumference \:of\: the\: circle\: =\: 2\:\pi \:r}⟼Circumferenceofthecircle=2πr

\longmapsto\mathsf{Circumference \:of\: the\: circle\: =\: 2\times\:\dfrac{22}{7}\:\times\:21}⟼Circumferenceofthecircle=2×

7

22

×21

\longmapsto\mathsf{Circumference \:of\: the\: circle\: =\: 2\times\:22\:\times\:3}⟼Circumferenceofthecircle=2×22×3

\longmapsto\mathsf{Circumference \:of\: the\: circle\: =\: 44\:\times\:3}⟼Circumferenceofthecircle=44×3

\longmapsto\mathsf{Circumference \:of\: the\: circle\: =\:132m }⟼Circumferenceofthecircle=132m

So the circumference of the circular swimming pool is 132m

αnswer :-

\boxed{\mathsf{\bigstar\:\:Circumference\:of\:the\:circular\:swimming\:pool\:=\:132m\:\:\bigstar}}

★Circumferenceofthecircularswimmingpool=132m★
