The radius of the base and the height of a right circular cone are 7 cm and 24 cm respectively. Find the volume and total surface area of the cone.

Radius of the base of a right circular cone is 7 cm.
Height of a right circular cone is 24 cm.
Volume of a right circular cone = π r²h =× 7 × 7 × 24 = 1232 cm³
Slant height of the cone = === 25 cm³
Total surface area of a right circular cone = πr(r + l)
                                                           = × 7(7 + 25)
                                                           = × 7 × 32
                                                           = 704 cm².
