Question

Find the ratio of Total Surface Area and Lateral Surface Area of cylinder if its radius and height are 7cm. and 8cm. respectively
​

Answer 1

Answer:

$Ratio =15:8$

Step-by-step explanation:

$\frac{TSA \: of \: cylinder}{ LSA \: of \: cylinder} \\ = \frac{2\pi r(h + r)}{2\pi rh} \\ = \frac{h + r}{h} \\ = \frac{7 + 8}{8} \\ = \frac{15}{8} \\ = 15 :8 \\ \:Therefore, \: the \: ratio \: is \: 15:8.$
