Question

A solid wooden cylinder of height 8cm and radius 3cm is cut in two vertical axis of symmetry. Calculate the total surface area of the two pieces

Answer 1

first calculate the surface are of complete cylinder

Answer 2

=2*pi*r*h+2pi*r^2

Answer 3

can u find it ???

Answer 4

yup 54pi?

Answer 5

wait no66pi

Answer 6

2*pi*3*8+2*pi*3^2
=48pi+18pi=66pi

Answer 7

yeah u r right

Answer 8

now if cut down in two part so surface area will be half for both

Answer 9

yup but i dont get it next

Answer 10

cylinder cut in 2equal part so surface area will divide in 2 part

Answer 11

66/2=33pi each

Answer 12

then?

Answer 13

but after cutiing the base will be rectangle

Answer 14

with dimensino
length=8 and width=3

Answer 15

surfce area=8*3=24
so surface area of each = 33pi +24=

Answer 16

yup i got it till there

Answer 17

after cutting it base will be rectangular

Answer 18

thnx ill try it

Answer 19

and the total surface area is twice that area

Answer 20

oh wait ,

Answer 21

wait thats not right it should be 303cm squared thats what the answer says

Answer 22

yah perfecr ig to that too thnx anyways~
