What is the curved surface area of the cone of radius 7cm and height 24cm * 1 point?

CSA of cone = πRL = 22/7 × 7 × 25 = 22 × 25 = 550 cm².

What is the formula for curved surface area of a cone?

The curved surface area of the cone with slant height and diameter can be found by using the formula S = π(D/2)l, where D is the diameter and l is the slant height.

What is the curved surface area of a cone of radius r?

Help improve it. The surface area of a cone is equal to the curved surface area plus the area of the base: π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr, where r denotes the radius of the base of the cone, and L denotes the slant height of the cone. The curved surface area is also called the lateral area.

What is the area of the curved surface of a right circular cone of radius and height?

π r l
For a right circular cone of radius ‘r’, height ‘h’ and slant height ‘l’, we have; Curved surface area of right circular cone = π r l. Total surface area of a right circular cone = π(r + l) r.

Surface Areas and Volumes. Curved surface area of a hemisphere with radius 7 cm is: 308 cm.

What is the curved surface area of hemisphere icecream if the base radius is 7 cm?

the curved surface area of hemisphere is the base radius is 7 cm is 308 cm².

How do u find the height of a cone?

The cone height formula calculates the height of the cone. The height of the cone using cone height formulas are, h = 3V/πr 2 and h = √l2 – r2, where V = Volume of the cone, r = Radius of the cone, and l = Slant height of the cone.

What is curved surface area?

Curved Surface Area- The curved surface area is defined as the area of only curved surface, leaving the circular top and base. Total Surface Area- It is the area of the curved surface as well as the bases.

How many curved surfaces does a cone have?

one curved surface
3D shapes such as cones and cylinders have a curved surface as well as flat surfaces. A cylinder has 2 flat surfaces and one curved surface. A cone has one flat surface and a curved surface.

How do you find the curved surface area of a right circular cone?

Curved surface area of a cone is defined as the area or region covered by the curved surface of a right circular cone. It can be calculated using the formula, Curved surface area of a cone = πrs = πr√(r2+h2), where ‘r’ is the radius, ‘s’ is the slant height, and ‘h’ is the height of the cone.

How do you find the surface area of a right circular cylinder?

The general formula for the total surface area of a cylinder is T. S. A. =2πrh+2πr2 .

How to find the surface area of a right circular cone?

A right circular cone is a circular cone whose axis is perpendicular to the base. Surface area of cone = πr (r+√ (h 2 +r 2 )) where r is the radius of the circular base. h is the height of the cone. Slant height of the cone, L = √ (h 2 +r 2) Therefore, Surface area = πr (r + L)

How do you find the length of a curved cone?

Hence, Length of entire curved boundary = circumference of base = 2 π × r (where r is the radius of the base) The Total surface area of a cone includes the curved surface as well as area of its base, which is given as- A circular cone is the one with the circular right section.

What is the formula to find the volume of a cone?

Circular Cone Formulas in terms of radius r and height h: Volume of a cone: V = (1/3) π r 2 h. Slant height of a cone: s = √ (r 2 + h 2) Lateral surface area of a cone: L = π rs = π r√ (r 2 + h 2 ) Base surface area of a cone ( a circle ): B = π r 2.

How do you find the slant height of a cone?

The slant height of a cone is calculated using the formula s=√ (r 2 + h 2) units, where “r” is the radius and “h” is the height of a cone. What is the lateral surface area of a cone? The lateral surface area of a cone is calculated using the formula, LSA =πr√ (r 2 + h 2) square units. This is all about the area of a Cone.
