Question 1055913: A net of a solid shape. The two circular faces are congruent and each has a diameter of 7cm nd a height of 25cm
A) Which solid shape can be formed from this net?
B) Calculate :1) The total surface area
2)The volume of this solid shape formed
C) If this solid shape is hollowed but left closed on one end of the circular faces which of these aspects between surface are and volume will be affected?
Calculate the new value of the affected aspect in ml if it is volume and in m*2(m squared) if it is area

Hi,

 .

A) Cylinder

B) 

   S = 2pi%2Arh+%2B+2pi%2Ar%5E2 = 2pi%2A7%2A25+%2B+2pi%2A7%5E2

   V =+pi%2Ar%5E2+%28h%29 = +pi%2A7%5E2+%2825%29

C) Surface Area

Snew = 2pi%2A7%2A25+%2B+pi%2A7%5E2
