Step-by-step explanation:
curved surface area=440cm^2
total surface area=748 cm^2
volume= 1540 cm^3
h = 10cm
r=7cm
=2×
7
22
×7×10
=44×10
=440cm

NOW,
TSA cylinder =
2 \pi \: r(h + r)2πr(h+r)
\begin{lgathered}= 2 22÷7 7(10 + 7) = 44 = 748 cm
=2×
7

×7(10+7)
=44×17
=748cm

NOW,
volume of cylinder =2hπr
