Find the area of the purple portion.

Everyone can be a mathematician or a scientist,there are other sectors that improves human existence too,so if I or my children don't know this does not make me a failure

You that know,let your impact be felt,not looking down on who doesn't know

I like your disposition very matured!.
But will u speak calmly like this to a child that made a mistake in English language, not to forget that English is just a subject like mathematics.
My opinion: the way we treat mathematics is not fair.
We make joke with us not understanding it and everyone laugh, but if anyone try that in English everyone including the village people begin to advice him of how he need to improve for his good.

Answer is 13.18 m²

@ifada123
Before I post my answer, I must first appreciate you for the questions. Keep them coming. Make sure you correct my errors and show the correct answers.

The area A of the purple region is :
A = (5/6)(10π - 9√3) ≈ 13.189557 m²

Thank you sir for the appreciation.

I am in a meeting now, I will solve later and send you feed back
Please bear with me.

Subtract area covered by 15 hexagons from area of circle;
π(5²) - 15(3√3 / 2) = 39.568673169

Divide by 3 to get area of purple sector:
39.568673169 / 3 = 13.189557723 m²

360/6=60 thus each triangle is equilateral with 6

triangle inside an hexagon

Area of hexagon = 6× area triangle

Area triangle =0.5× 1×height

Were height =0.5tan60

Area of triangle=0.5×1×0.5×tan60

=0.433013

Area of hexagon =6×0.433013

=2.598076

Area of all hexagon =15×2.598076

=38.971145m^2

Area of circle =22/7 x25=

Area of purple =(area of circle -area of all hexagon)/3

=(78.539861-38.971145)/3

=13.187592m^2

@ifada123

I like your questions, they involve simple maths and demand more of one's ability to think rather than immense knowledge of maths. Keep them coming.

Thank you sir, I will bring more soon

Shit.... I hate mathematics! Wow I typed " I hate" and next thing "Mathematics " popped up on my phone

how much do u HV in ur acct you that know how to do it.

If you don't know this is what is puting money into my account and it is consistent and improving.
I am a boss of my own with this.
So stop hating school now scam crew!

Everyone can do it sir , it just depends on your commitment,

Sir what method did you use in converting me into a male?

ifada123:

I believe everyone can know maths. They just have to give it a try, be brave and work. Mathematics is sweet. Personally, I think it improves the way one thinks logically, it did for me.

BecaciaBarbie:

Sir what method did you use in converting me into a male?

Smile
I am sorry for that.
But when the Bible use "him" "he" I wonder why that passage is also applicable to female.
Just kidding.....
Once again I am sorry madam.

I can't solve it. Mathematics and I are enemies, no matter how hard I try, it just doesn't stick in my brain.

OP, I can't solve it and I won't bother. Instead, I'll employ you and pay you to solve it for me. I'll then add other factors and make an executive decision that makes me earn your annual salary in 2 days.

Those who can solve it better and faster than you go on strike before they can receive pay increase. So, what's your noise about?

Pls sir can I a formular to hit baba ijebu lotto jackot? a great mathematician should be able to work that out

your method is longer, you don't have all the time if its Jamb question

Nigeria employ the Europeans to search for minerials in Nigeria
The Europeans found mineral deposit
Nigeria ask them which mineral
The Europeans tell them what they felt like telling them
Nigeria ask what quantity
The Europeans tell them the quatity the felt like telling them
Nigeria ask what is the cost
The Europeans tell them how much they felt like buying it
They gave Nigeria little money extract as much as they want and refine the minerals and sell the back to Nigeria at a price they fell like selling it,
WHO IS THE SLAVE?

If you don't know you are at my mercy, if you don't know what you employed my to do, don't bother and see the way your inherited wealth source might crumble because you employ people to do every single thing for you(including your signature),
What many of you don't understand is not everyone will be futunate as dangote and the few others,
Why not know and excel in what everyone can learn and do with a probability of close to 1 (I know you still don't understand, you can employ some to interpret this)

That's true, I have shorter ways but I like using basic JSS knowledge to solve shapes, so that everyone will see the concept, and how it was built up

Thank you sir I appreciate,
It is a wise decision you have made, wanting your children to be good in the subject,
I will advice you to find someone close to your area and employ him/her.
You know what? Many kids run away from their dream career when they see maths is involved,
I don't know you might even be a victim.
Your kids will ever be grateful if you give them this opportunity.
