1.	:) Diameter of the base of a cone is 10.5 cm and its slant height is 10 cm. Find its curvedie ite slant height is 21 m and diameter of its basesurface area.
Answer» Diameter= 10.5 cm Radius (r) = 10.5/2 cm = 5.25 cm Slant height (l) = 10 cm Curved surface area of the cone = (πrl) =(22/7 × 5.25 × 10)=165 cm² Hence, the curved surface area of a cone

Answer»

Diameter= 10.5 cm

Radius (r) = 10.5/2 cm = 5.25 cm

Slant height (l) = 10 cm

Curved surface area of the cone = (πrl)

=(22/7 × 5.25 × 10)=165 cm²

Hence, the curved surface area of a cone
