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 surface area of a cone of base diameter 30 cm and height 40 cm?

Answer :- Surface area of the cone is 2013cm².

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.

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 .

Where is the radius located in a cone?

A cone is a solid composed of a circle and its interior ( base ), a given point not on the plane of the circle ( vertex ) and all the segments from the point to the circle. The radius of the cone is the radius of the base.

How do you find the radius of a circular base of a cone?

How to Find the Radius of Cone If Base Area of a Cone is Given?

1. Step 1: Identify the given dimensions of the cone and assume the radius of the cone as “r”
2. Step 2: Substitute the given values in the formula A = πr2.
3. Step 3: Solve for “r”.
4. Step 4: Write the obtained answer in units.
