Question

A cylindrical vessel open at the top has a radius of 10 centimetre and height 14 cm find the total surface area of the vessel. 1 is equal to 3.14

Answer 1

radius of cylinder=10cm=r
ht. of cylinder=14cm. TSA of cylinder= CSA of cylinder +base area.
$2\pi \: r \: h + \pi \: r {}^{2} \: h$
$2 \times 3.14 \times 10 \times 14 + 3.14 \times 10 \times 10$
$439.6 + 314 = 753.6 \: sq \: cm$
