Question

he height of a tent is 9m it's Base diameter is 24m what is slant height. Find the cost of the canvas cloth required if it costs 14 per Sq.m

Answer 1

Answer:

$\pink{given \: height = 9m}$

$\blue{given \: diameter = 24m}$

$\pink{then \: radius = 12m}$

$\blue{we \: know \: that \: slant \: height(i) = \sqrt{h ^{2} } + {r}^{2} }$

$\pink{ = \sqrt{9 }^{2} + {12}^{2} }$

$\blue{ = \sqrt{81} + 144}$

$\pink{ = \sqrt{225} }$

$\blue{= 15m}$

$\pink{we \: know \: that \: curved \: face \: area = \pi \: rl}$

$\blue{ = \frac{22}{7} \times 12 \times 15}$

$\pink{ = \frac{3960}{7}}$

$\blue{cost \: of \: {1m}^{2} canvas = 14}$

$\pink{cost \: of \: \frac{3960}{7m^{2} } canvas}$

$\blue{ = \frac{3960}{7 \times 14} }$

$\pink{ = 7920}$

$\red{therefore \: the \: cost \: of \: canva \: required \: to \: make \: the \: tent \: = 7920}$
