What is the surface area of a cone with the height 24 and the base is 7?

A cone with height 24 and the base diameter 7 has a surface area of 305.17 units2


The total surface area of a cone if its slant height is 21'm and its diameter of its base is 24'm is?

Total surface area of cone = (pi*radius*slant height) + (pi*radius2) Area = (pi*12*21) + (pi*122) = 1244.070691 or about 1244 square m


A right circular cone has radius 5cm and height 8cm Find the lateral surface area of cone?

This cone has a lateral surface area of approximately 226.73cm2


A right cone has a base diameter that is 12 cm and a slant height that is 45 cm What is the surface area of the cone?

Formula for surface area of a cone: π=pi (3.14159265) l=slant height, r=radius. πr2+πrl π62+π6*45=x 36π+270π=x 306π=x 961.33 cm2


What is the area of hollow cone?

Find cone base area using a circle's formula, which is pi times (radius squared). Find cone slanted area with this formula:half of the length of the side, times the circumference of the base.. Add the results to get the total surface area.Measure the cone's circumference with this formula: C = pi * d. C is circumference and d is its diameter. Measure the diameter, which is a line from the base's one side, through its center, to the opposite side.Calculate cone slant height from its top to its base's side. Use your slant height and circumference measurement to calculate cone slanted area. Use step one's formula, where "s" is the slant height, and C is the circumference.4 Add your results for cone base area and cone slanted area to get the total cone surface area.

What is the surface area of a cone that has a diameter of 6 inches and a height of 7 inches?

Now that depends on if you mean outside surface area. A cone has an inside surface area too. Just adding my two cents. Not even good at math. But I can debate a point til the death!


How do you find the surface area of a circular cone with a height of 3.76 ft and a base diameter of 5.74?

Entire surface area of a cone = (pi*radius2)+(pi*radius*slant length) Use Pythagoras' theorem to find the slant length
