Use a calculator and you'll get yurh answer
It depends on what information you have: its radius and slant height, radius and volume, radius and surface area, surface area and volume, etc.
The answer is squareroot r2+h2 squareroot radiusxradius + heightxheight
The total curved surface area is 888.5 cm2
Calculate the volume of full cone. For this you need to reproduce the cone surface upto the point where radius becomes zero.Then deduct the volume of the portion which is cut from the full volume. You can't multiply the height to the average of bottom area and top area. Because area (pi.r^2) is the second degree function of radius, not first degree.
A circular cone has a height of 17mm and slant height of 21mm.find (1) the volume (2) the total surface area, of the cone the total surface area, of the cone Help me please Thank

Some of many examples are:- Finding the circumference of a circle Finding the area of a circle Finding the surface area of a sphere Finding the volume of a sphere Finding the surface area of a cylinder Finding the volume of a cylinder Finding the volume of a cone Finding the surface area of a cone
It depends on what information you have: its radius and slant height, radius and volume, radius and surface area, surface area and volume, etc.
The answer is squareroot r2+h2 squareroot radiusxradius + heightxheight
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
no

No, it never can equal one third of the lateral surface area:If the base of the cylinder and cone has radius r, and the height of the cone and cylinder has height h, then:Lateral surface area of a cone = πr√(r2+h2)Lateral surface area of a cylinder = 2πrhThe lateral surface area of a cone equals one third the lateral surface area of a cone when:πr√(r2+h2) = 1/3 x 2πrh⇒ √(r2+h2) = 2/3h⇒ r2+h2 = 4/9h2⇒ r2 = -5/9h2But a square number can never be negative, so this is impossible.However, the volume of a cone is one third the volume of the cylinder with the same radius r and height h:Volume cone = 1/3πr2hVolume cylinder = πr2h
The volume of a cone can be calculated using the formula V = (1/3)πr^2h, where r is the radius and h is the height. To find the radius, use the formula A = πrℓ, where A is the curved surface area and ℓ is the slant height. Given A = 550 cm and h = 25 cm, you can find the radius and then calculate the volume of the cone.
It is 3:1. This is because volume of a cone is pi/3*r*r*h while vol of a cylinder is pi*r*r*h.
