A right cylinder has a diameter of 30mm and a height of 40mm. what is the volume of the cylinder?

Solution,

Diameter=30 mm

Radius=30/2=15 mm

height=40mm

Now,

Volume of cylinder= pi *(r)^2*h

=3.14*(15)^2*(40)

=3.14*225*40

=28260 mm^3

Hope it helps

Good luck on your assignment

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
