3. Cone (Surface Area & Volume)
Cone is like an Ice Cream
place or the hat of farmer
in Indonesia. But What we
want to discuss is how to
find the surface area and
volume of cone. Let see
the video in the next slide.
4.
5. Surface Area Of Cone
From that video, we can conclude that Cone is
consist of a circle and a lateral area of cone. So
the formula is like this :
r = radius
l = slant height
¶ = Phi = 3.14 =22/7
6.
7.
8. Volume Of Cone
From that video, we can consist that the
formula is like this:
¶ = Phi = 3.14 =22/7
r = radius
l = slant height
9. Sphere (Surface Area & Volume)
Sphere is like a foot ball in our daily
life.
But, How we can find the volume and
surface area of sphere. Let see the
video in the next slide.
10.
11. Surface Area Of Sphere
From that video, we can conclude that the surface
area of sphere is consist of 4 times area of circle.
The formula SA = 4 times area of
is like this:
circle.
= 4 ( ¶r² )
¶ = Phi = 3.14 =22/7
r = radius
12.
13. Volume Of Sphere
From that video, we conclude that the formula of
volume of ball is : V = 4/3 ( Area of circle)
= 4/3 ( ¶r² )
¶ = Phi = 3.14 =22/7
r = radius
14. Exeersice
1) Find the surface area and volume of cone that has radius of 7cm
and height of 24cm !!!
2) Find the surface area and volume of sphere that has radius of
14cm !!!
3) If known that surface area of sphere is 616 cm² , find the radius
and the volume of sphere !!!
4) If known that volume of cone is 256.67cm² , find the radius and
the surface area of cone!!!
