Question

Q4. Curved surface area of a right :
circular cylinder is 1.76 metre
square. If the radius of the base of
the cylinder is 1.4 decimetre , find
its height
*​

Answer 1

$curved \: surface \: area \: \: of \: cylinder \: = 1.76 {m}^{2} \\ radius \: of \: base \: of \: cylinder = 1.4dm = 1.4 \times 10 = 14 \: meters \\ curved \: surface \: area \: of \: cylinder = \pi rh \\ 1.76 = \frac{22}{7} \times 14 \times h \\ \frac{176}{100 \times 44} = h \\ \\ 0.04metres \: = h$
