Q6 its one question.

Area of semi circle = 1/2 * pie * 3^2
=9/2 * pie
Area of triangle = 1/2 * 9 * 6
= 27
Add both to get total area

faces = 12
vertices =24
edges = 36
is this right?

yup but the faces are 14? how?

yup but the faces are 14? how?

just count them
1 at the top, 1 at the bottom
4 on the sides
8 traingles
i guess that makes it 14..

what are vertices? i'm confused btwn vertices and edges!

vertices are like the Konas the corners the tips of the end..
and the edges are like the lines joining the vertices..

oh thanks.

can anyone tell the relationship between mass and length in similar objects ???? help ASAP !!!

 

[kitecrystal]

use the concept x^1\2=square root of x.......​

answer is 3\2 ​

sorry power was off so replying v.late...
solution...square root(2*2*3)\(square root 3*3*3)
=2*square root(3)\3square root(3)
=square root (3) cancel,answer left =2\3...hope u understand

 

[kitecrystal]

can u please solve?

solution...square root(2*2*3)\(square root 3*3*3)
=2*square root(3)\3square root(3)
=square root (3) cancel,answer left =2\3...hope u understand​

can anyone tell the relationship between mass and length in similar objects ???? help ASAP !!!

(Mass of object1/mass of object 2)=(length of object 1/length of object 2)^3

 

[Ahmedfj]

(Mass of object1/mass of object 2)=(length of object 1/length of object 2)^3

but cube is only used for volume .. isnt it ?

anyone?
formula for calculating the interior angles of a polygon...:|
QUICK PLZ!!

180(n-2)/n
ye formula tab he apply hoga jab regular polygon ho

 

[Spidey21]

180(n-2)/n

where n is??
