The slant height of a cone is 12 cm and radius of the base is 4cm, find the curved surface of the cone?
74 π cm2
36 π cm2
48 π cm2
24 π cm2
Explanation:
Curved surface of the cone = $\pi \times base \times height $
=> $\pi \times 4 \times 12 $
=>$48 \pi cm^{2} $
Curved surface of the cone = $\pi \times base \times height $
=> $\pi \times 4 \times 12 $
=>$48 \pi cm^{2} $
