Measure the dimensions of earthen pots (assuming spherical/cylindrical in shape) and then
compare their surface areas and find the volume of water in liters
(Hint: To find the radius of earthen pots find the circumference of the middle part of the pots
with the help of measuring tape.)
Answers
Measured the dimensions of earthen pots and calculated radius , surface area and volume
Step-by-step explanation:
Circumference = 2πR
Surface area = 4πR²
Volume = (4/3)πR³
Circumference Radius Surface area Volume V S/V
cm R ( cm) S ( cm²) V ( cm³)
70 11.14 1559.72 5792.19 0.27
98 15.60 3057.05 15893.78 0.19
112 17.83 3992.88 23724.83 0.17
