Answer:
Step-by-step explanation:
lateral surface area=2*22/7*r*h=2*22/7*20*h
given lateral surface area=1000=880h/7
h=7000/880=700/88=350/44=175/2=87.5
volume=(22/7)*20*20*(175/2)=22*20*20*25/2=22*20*10*25=110000

Step-by-step explanation:
le the r be X
height = h= 5 cm
lateral surface = 94.2 cm square
2πrh = 94. 2
2 X 3.14 X r X 5 = 94. 2
r= 94.2 divide 2 X3.14 X r
= 3 cm
