Help help help! Lateral area means total surface area I believe! Thanks!

Answer 1

$\qquad\qquad\huge\underline{{\sf Answer}}☂$

Let's solve ~

$\qquad \sf \dashrightarrow \:lateral \: surface \: area = \pi rl$

$\qquad \sf \dashrightarrow \:la = \pi12 \times 15$

$\qquad \sf \dashrightarrow \:la =180 \pi$

Therefore, the lateral surface area of cone = 180 pi in²
