The height and radius of cone are 4 cm and 3 cm respectively. Find the curved surface area of cone.
14π cm2
16π cm2
15π cm2
12π cm2
Slant height is given by l=√h2+r2 l=√42+32 l=√25 ⇒l=5 cm Hence, curved surface area of cone will be =πrl =π ×3 × 5 =15π cm2
The height and radius of cone are 4 cm and 3 cm respectively. Fnd the curved surface area of cone.
The height and radius of cone 4cm and 3 cm. Fnd the curved surface area of cone.
A cone of radius 3 cm and slant height 5 cm has curved surface area of:
