Question

an open (without the top lid) cylinder with base
radius 10.5 cm and height 16 cm.find the total surface area,volume and curved surface area
​

Answer 1

Answer:

total surface area----2pie×r(r+h)

=2pie×r^2+2pie×r×h

with open lid

2pie×r^2-pie×r^2+2pie×r×h

=pie×r^2+2pie×r×h

=346.5+1056

=1402.5

volume------pie×r^2×h

=22/7×10.5×10.5×16

=5544

curved surface area----2pie×r×h

2×22/7×10.5×16

=1056

hope this answer will be right.....
