Provided that the "slant height" is actually the length of the slant (from one edge of the circle to the point on top), we can just plug in 5 for r and 7 for s into this formula:
SA = pi*r2 + pi*r*s
SA = pi*52 + pi*5*7
SA = 60*pi = 188.5 square meters.
The surface area of a right cone with a radius of 8 and a slant height of 15 is: 377 units squared.
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 slant height of 6 and a radius of 7 has a total surface area of about 245.04 square units.
It depends on what information you have: its radius and slant height, radius and volume, radius and surface area, surface area and volume, etc.
Surface Area = Pi*radius(radius + slant height)
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
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
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.
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
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.
It depends on what information you have: its radius and slant height, radius and volume, radius and surface area, surface area and volume, etc.
Surface Area = Pi*radius(radius + slant height)
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
