Measure it.
the cone base formula
The axis of a right circular cone is perpendicular to every radius or diameter of the base.
Entire surface area of a cone = (pi*radius2)+(pi*radius*slant length) Use Pythagoras' theorem to find the slant length
The volume of a cone is base×height÷3base×height÷3=144×π×10÷3base×height÷3=1440π÷3
87766.14 mm cubed. Radius squared times pi find the area of the base. Then, we take it times the height (77) and since its a cone we divide by 3.
The base radius ( or diameter) and the height
The base of a cone is a circle. The area of a circle is found by multiplying the diameter by Pi.
the cone base formula
The height would be The square root of the square of the slant surface length minus the square of the radius of the cone at the base.
The volume of a cone 4 feet high with a base diameter of 13 feet is: 177 cubic feet.
The diameter squared multiplied by Pi/4 Area = Pi/4 x D2
The volume of a cone that has a height of 8.5 yards and a base with a diameter of 8 yards is: 142 cubic yards.
The axis of a right circular cone is perpendicular to every radius or diameter of the base.

A cone with height 24 and the base diameter 7 has a surface area of 305.17 units2
The lateral area of a right circular cone with a base diameter of 4 m and a slant height of 15 m is: 94.25 m2
That depends what you are given. If you have an actual cone, you can measure the diameter of course.
