Answer:
Step-by-step explanation:
let r be radius of the cylinder.
volume of cylinder=πr²h
1728π=πr²×12
r²=1728 π/12π=144
r=√144=12
diameter=2r=2×12=24 cm

Answer:
Let, the c.p be x.
Given,
profit % = 20%
S.P = rs 816
c.p = x
We know,
profit = p% of c.p
= 
* x
= 
now,
C.p = profit + s.p.
x = + 816
x = 
5x = x + 4080
5x-x = 4080
4x = 4080
x = 
x = Rs 1080
Hence, the c.p is Rs. 1080
