Hey! I couldn't find a section here that was dedicated to this topic, so i posted here:
I'm having trouble.
In my Textbook it has: Use (pie sign) = 3.14
1. (a) Draw the net of this cylinder/[it's a normal cylinder only it's on it's side and the length is 10 cm, and the width is 8 cm.
(b) What shapes have you drawn?
(c)What is the radius of each circle?
(d) What is the area of each circle?
(e) what are the dimentions of the rectangle?
(f) What is the area of the rectangle?
(g) What is the total surface area
And well in my other textbook it has the answers like:
a)a rectangle with 2 circles, one on each side,
b)1 rectangle 2 circles
e)25.1 cm x 10 cm =
I donít see how they got (d) and from then on!
And for workings they have: A = Pie R 2 (s is squared)
= pie x 4 x 4
= 50.3 cm2
C = pie d
= pie x 8
= 25.1 cm
