Question

the v olume of cylinder is 150 22÷7 cu.cm and its height vis 6cm . find the area of its tsa and lsa

Answer 1

Volume of cylinder= 22/7*r^2*h
Given vol. =150 22/7cm^3
Height= 6 cm
So,
22/7×r^2×6= 150 22/7
r^2 *6= 150
r^2= 25
r=25^1/2
r= 5cm
Now,
LSA= 2×22/7×5×6=60 22/7 cm
TSA= 2×22/7×5(5+6)= 220 22/7 cm
