Question

the perimeter of base of cylinder is 55cm and height is 10cm find csa​

Answer 1

Answer:

$we \: know \: that \: the \: circumference \: is \: 55 \: cm \: then \\ 2\pi \: r = 55 \\ 2 \times \binom{22}{7} \times r = 55 \\ r = 8.75 \\ then \: the \: height \: is \: given \: as \: 10cm \\ 2 \times\pi \times r \times h = 2 \times \binom{22}{7} \times 8.75 \times 10 \\ then \: according \: to \: the \: calculator \: the \: answer \: is \: 550cm$
