MORE ON GEOME-TREE🌳

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💡

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
