Question

Find the total surface area of the cone whose base radius is 8cm and slant height is 6cm​

Answer 1

Step-by-step explanation:

$total \: surface \: area \: = \pi \times r(l + r)$

$t.s.a = \frac{22 \times 8 \times (6 + 8)}{7}$

$t.s.a = \frac{22 \times 8 \times 14}{7}$

$t.s.a = 22 \times 16$

$t.s.a = 352 \: {cm}^{2}$
