The total surface area is 400.21 square inches. The lateral surface area is 287.11 square inches.

Total surface area = 314.16 square inches. Lateral surface area = 157.08 square inches.

The lateral area is 188.5 square inches. The surface area is 301.59 square inches.

Surface Area = Pi*radius(radius + slant height)

For a right cylinder, if the surface area is 2,072.4 and the radius is 15 the height will be 7 (6.99) units.

The surface area of a right cone with a radius of 8 and a slant height of 15 is: 377 units squared.

A right cone with a radius of 4 and a slant height of 13 has a total surface area of about 213.63 units2

A right cone with a slant of height of 7 and a radius of 5 has a total surface area of approximately 188.5 units2

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.

Slant height is 7.81 inches.

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 surface area is 552.92 units2

The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2

wow nice job copying from your homework

Entire surface area = (2*pi*radius2)+(pi*diameter*height)

75.4 units2

SA = about 622.03 units2

It is 552.9 square units.

Uisng the lateral area and tha radius, you should be able to find the height of the cone. Using the height and radius as the legs of a right triangle, use the Pythagorean Theorem. The hypotenuse is the slant height.

417.83 units squared

The answer is 198*pi sq units.
