Question

Find the surface area of the figure. Round the the nearest hundredth.

Answer 1

Answer:

Step-by-step explanation:

surface area of cylinder=2πrh

SA=1/2×2×π×3×25+2 ×(1/2×π×3²)=75π+9π=84π≈84×3.14≈263.76 cm²

if lowerside is also counted  then area of lower side=25×6=150

total surface area=263.76+150=413.76 cm²

if we take π=22/7

84 π=84×22/7=12×22=264 cm²

if base is also counted then area=264+150=414 cm²
