Can someone help? I'm confused :p

4747.68 sq. cm

Step-by-step explanation:

First find the circumference of the circular part of the can. The equation is C=2pi(r). Fill in the values and the circumference should come out to be 37.68. Remember you are trying to cover the can, so one straight line won't cut it. You have to multiply by 7, or the height of the can.

Then you have it, 263.76 sq. cm to cover one can. Since they are asking for 18, multiply by 18 and you will have 4747.68.

Brainliess would be appreciated!

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

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
