Area of Circle = π - Proof | Geometry Olympiad Problems

[@upsckart7024]

r=∆/s = {(4×3)/2} / {(4+3+5)/2} = 6/6=1 Area = π r^2 = π [1]^2 =π

[@somakoshi3681]

,A=1/2p×r. ...1/2bh=1/2×4×3=6. 6=1/2(4+3+5)×r ....=1/2×12×r ...6=6r r=1

[@michaeldoerr5810]

That is a proof that I better practice on. And tbh this proof is applicable to ALL primitive Pythagorean triples. I am honestly quite surprised that there has yet to be a compendium of primitive triples theorems or theorems regarding primitive triples!!!

In Base , two parts : r and (4-r) In Perpendicular , two parts : r. and (3-r) In Hypotenuse ,two parts : (3-r) and {5-(3-r)} {5-(3-r)} = (4-r) r= 1 Area= Π

3-r+4-r=5 2r=7-5 So r=1 So Blue area=π(1)^2=π=3.14 square units.

[@Deku-b9u]

Actually π exact value is not 3.14.exact value of π is Smaller than 3.14.

You can't find the centre of circle by imagination. There's a method to find it.... Can you define

[@muhammadashraf-mn2si]

At the end the answer pronounced is what was to be required. So the answer is pi

[@ALEMBERHE-k6e]

the answer is 3.14 square units

[@sarojghosh9484]

No! area is pi x r square = pie (not 1)

[@pundalikpastay781]

Who told about centre of circle???

[@muhammadashraf-mn2si]

One can't find the centre of circle by imagination... He is not telling the method and similarly he draws a square but doesn't tell how he can say it is a square without describing the formula or method

इस वीडियो में जो टीचर पढ़ा रहा है क्या मैं उसका नाम जान सकता हूं?

Anarudh Maurya

[@subhraguha2443]

Area is π , why you told 1sq unit ?

Mujhe to samjh me hi nahi aaya😂😂😂
