Question

the curved surface area of a right circular cone of height 15cm and the base diameter16cm is​

Answer 1

Answer:

Step-by-step explanation:

h = 15 cm, r = 8 cm

So,

l=sqrt (r^2+h^2)

=sqrt (8^2+(15)^2)

=17cm

∴ Curved surface area :

=πrl

=(π×8×17) cm^2

=136π cm^2

Answer 2

$\huge{\underline{\underline{\mathbb{\red{solution}}}}}$

$Here ,\\ h = 15 cm \: \: \: r = 8cm \\ Now, \\ l = \sqrt{ {r}^{2} + {h}^{2} } \\ = \sqrt{ {8}^{2} + {15}^{2} } \\ = \sqrt{64 + 225} \\ = \sqrt{289} \\ = 17cm \\ \\ \\ Curved \: surface \: area \: = \pi \: rl \\ = (\pi \: \times 8 \times 17) c {m}^{2} \\ = 136\pi \: c {m}^{2}$
