Question

2) A cylinder has circular base of diameter 28cm and height of 11cm.
Find i) total surface area ii) volume​

Answer 1

Answer:

diameter= 28cm

radius= 28/2 = 14cm

height= 11cm

TSA= 2πr+2πr^2

= 2×22/7×14+2×22/7×14^2

= 44×2+44×28

= 88+1232

= 1320

Answer 2

Step-by-step explanation:

hey mate here is your answer:

1)total surface area of cylinder:

2πr(r+h)

=2×22/7×14(14+11)

=4×22×25

=2200cm^2

2) volume of cylinder:

v=πr^2h

=22/7×14×14×11

=44×14×11

=6776cm^3
