Base surface = pi*r2 Curved surface = pi*r*l where l is the slant height
If the vertical height (h) is given rather than the slant height, then use Pythagoras: l2 = h2 + r2

area base hight
The formula for the area of a cone is one-third multiplied by the base multiplied by the hight.
the cone base formula
The answer is squareroot r2+h2 squareroot radiusxradius + heightxheight
The surface area of a right cone is the amount of square units that is needed to cover the surface of a cone. To find a surface area of a right cone , follow this formula S.A = 3.14rl + 3.14r(r) I hope it helped you.
