The total surface area of a cone is (pi)*r(r+l) where r = radius and l = slant height. So
(pi)5(5+7)
(pi)5(12)
188.4 Units Squared
The surface area of a right cone with a radius of 8 and a slant height of 15 is: 377 units squared.
Surface Area = Pi*radius(radius + slant height)
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
It depends on what information you have: its radius and slant height, radius and volume, radius and surface area, surface area and volume, etc.
A right cone with a slant height of 6 and a radius of 7 has a total surface area of about 245.04 square units.
The surface area is a function of the height (or slant height) and the radius of the base. So, the slant height is a function of the surface area and the base-radius. Since the latter is unknown, the slant height cannot be calculated.
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
A right cone with a radius of 4 and a slant height of 13 has a total surface area of about 213.63 units2
The surface area of a right cone with a radius of 8 and a slant height of 15 is: 377 units squared.
Surface Area = Pi*radius(radius + slant height)
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
It depends on what information you have: its radius and slant height, radius and volume, radius and surface area, surface area and volume, etc.
These dimensions are not possible for a right cone. The radius must be less than the slant height. If we reverse the dimensions (radius 6, slant height 9) the total surface area will be about 282.74 units2
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
A right cone with a slant height of 6 and a radius of 7 has a total surface area of about 245.04 square units.
A cone with a radius of 6 centimeters and a slant height of 9 centimeters will have a total surface area of approximately 282.74cm2
Slant height is 39.98 cm
