Question

Find the curved surface area of the cylinder whose diameter of the circular base is 56cm and height is 10cm.​

Answer 1

Step-by-step explanation:

We Have :-

$diameter \: of \: the \: circular \: base \: is \: 56cm \: and \: height \: is \: 10 \: cm$

To Find :-

$csa \: of \: cylinder$

Solution :-

$csa \: of \: cylinder \: = 2 \times \pi \times radius \times height \\ \\ \\ csa = 2 \times \pi \times \dfrac{56}{2} \times 10 \\ \\ \\ csa = 2 \times \pi \times 28 \times 10 \\ \\ \\ csa = 2 \times \dfrac{22}{7} \times 28 \times 10 \\ \\ \\ csa = 2 \times 22 \times 4 \times 10 \\ \\ \\ csa = 1760 \: cm^{2}$
