Hello GREATMINDS💡
So today on MATHSPEDIA A+🧠we shall discuss some more elementry formulae to find the Area/volume and perimeter of 5 more shapes

After the lesson if there is a part you don't understand feel free to comment

Fig 1.



So let's begin
1a. Area of a parallelogram  = b×h
(b=base, h=height)
1b. Perimeter of a parallelogram = Sides(a+a+b+b)
=2a+2b
=2(a+b)

Fig 2.


2a. Area of a rhombus=
There area several ways of finding the area of a rhombus

2ai. Area of rhombus with length of diagonals= (d1*d2)/2, * = ×

Fig 3.



2aii. Area of a rhombus with base and height = b×h

Fig 4.


2b. Perimeter of a rhombus= sum of the lenght of the rhombus
=l+l+l+l
=4L

Fig 5.


3a. Area of a kite when both diagonals are given= (d1×d2)/2

Fig 6.


3b. Perimeter of a kite= a+a+b+b
= 2a+2b
=2(a+b)

Fig 7.


4a. Volume of a sphere= 4/3πr3


4b. Surface area of sphere=4πr²

Fig 8.


5. Volume of a Cylinder= πr²h

Fig 9.




That's all for the day GREATMINDS💡
JOIN US NEXT TIME FOR
WAIT FOR IT
MORE SHAPES
If you were observant you'll know we've only talked about shapes
But what can I say
It's GEOME-TREE🌳 week
And besides we all know that Geometry keeps you in shape😉


Thank you
Have a nice day

So today on MATHSPEDIA we shall discuss some elementry Formulae to find the Area and perimeter of 5 shapes After the lesson if there is a part you don't understand feel free to comment Fig 1. So let's start 1a.  Area of a square = L×L= L square Where L= Length This is so because a square has all it's sides and angles equal 1b.  Perimeter of a square = L+L+L+L =4×L =4L Fig 2. 2a.  Area of a rectangle= L×B(L=length,B= breadth) 2b.  Perimeter of a rectangle= L+L+B+B                 =2L+2B                                               =2(L+B) 3a.  Area of a right angled triangle= 1/2×b×h (b=base, h=height) 3b.  Perimeter of a triangle= Sides a+b+c Fig 3. 4.  The area and circumference of a circle will be shown below👇: Fig 4. This image above👆 explains the circumference of a circle  Fig 5. The image above👆 shows the area and circumference of a circle. Fig 6. The image...

Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on Wait for it  5  Arithme-tricks😉 on multiplication of some digits After the lesson if there is a part you don't understand  feel free to comment Fig 1. So let's begin  1. Multiplication of two digit number by 11                           -1- 35 × 11 Step 1- Add both digits of the two digit number 3 + 5 = 8 Step 2- Place the result in between both digits 3_8_5 = 385 Fig 2. -2- 78 × 11= 858 Step 1 - Add both digits of the two digit number 7+8= 1 5 Step 2- Carry the one when the result is greater than nine 7+ 1= 8 Step 3- Place the result in between both digits  8_5_8=858 Fig 3. 2. Multiply by 9:       -1- 56 ×9= 504 Step 1- Multiply the number by 10: 56× 10 =560 Step 2- Subtract the original number from step 1 560 - 56= 504 Fig 4. 3. Multiply numbers between 11 and 19     -1- 14 ×18= 252 Step 1- Add the larger number to the rightmost digit of the other number 18 + 4=22 Step 2- Put a zero at the end of the...

Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on  5  more Arithme-tricks😉 on finding percentage % After the lesson if there is a part you don't understand  feel free to comment Fig 1. We all probably know that when we hear percentage we think of 100. So here are 5 amazing tricks that can help to find percentage of some numbers without the use of a calculator. So let's begin We'll start with some tips 1. Tip -1- 15% of 300 =45 Step 1- Calculate 10% 300/10 = 30 Step 2- Calculate 5% of the answer from Step 1. 5% of 30= 15 Step 3- Add step 1 and 2 30+15= 45 Fig 2. 2. 5% of numbers -1- 5% of 60= 3 Step 1- Divide the number by 10 60/10 = 6 Step 2- Divide the number from Step 1 by 2 6/2 = 3 Fig 3. 3. 20% of numbers   -1- 20% of 255= 51 Step 1- 20% = (100/5)% Step 2- 255/5 = 51 Step 3- 5=10/2 Step 4- Divide the number by 10 255/10 = 25.5 Step 5- Multiply the number from Step 4 by 2 25.5 × 2=51 -2- 20% of 255 = 51 Step 1- Divide the number by 10 255/10 ...
