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

Answer»

Volume of cone = πr^2h/3
3.14×7×7×24/3
1,230.88 cm^3
TOTAL SURFACE AREA of cone =πr(r+l)
FIRST find slant HIGHT
slant hight = root24^2+7^2
slant hight = root625
slant hight = 25 cm
3.14×7 (7+25)
703.36 cm^2
