Answer:
radius ra of Interior of internal cylinder is equal to 7 cm and its height is equal to 30 cm volume of a cylinder is equal to pie rki square×h=22÷7×7×30=22×30=660ans total surface are (2pie r h)=2×22÷7×7×30=44×30=1320

Answer:
external radius =8 cm
internal radius = 7 cm
hight = 30
internal volume= πrsquare h
22/7×7×30
22×30= 660
total surface area= 2πr(r+h)
2×22/7×8×7(8×7+30)
