Total area=csa of cone+csa of cylinder
=πrl+2πrh
=πr(l+2h)
=1.5π(2.8+2(2.1))
=1.5×22/7 (2.8+4.2)
=1.5×22/7(7)
=1.5×22
=33m²
Cost= 33× 500
= 16,500Rs
pls mark me as brainliest

Answer:
Step-by-step explanation:r
Total area = CSA of cylinder + CSA of cone
= 2πr₁h+πr₂l
= π(2*3/2*2.1+3/2*2.8)
= π(6.3+4.2)
= π*10.5 = 22/7*10.5 = 33 m²
Cost = 33*500 = ₹16500
Hope this helps.
Plz mark me as the brainliest.
