Question

when the radius of the cyclinder is double it's height find the relation between it's curved surface area and base area ​

Answer 1

Step-by-step explanation:

r=2h

$csa = base \: area(area \: of \: circle)$

$2\pi \: rh = \pi \: {r}^{2}$

substituting the value of r

$2\pi \: 2h \times h = \pi \: { {(2h)}}^{2}$

$\pi \: and \: \pi \:cancells$

$so \\ 2 \times 2 \times {h}^{2} = 4 {h}^{2}$

$4 {h}^{2} = 4 {h}^{2}$

so the relation between csa and base area

.....is that both r equal......

Answer 2

Answer:

The ratio between the CSA and Base Area : 1 : 1

Hence they are equal.
