The surface area of a cone can be calculated using the formula:
Surface Area = πr(r + l)
Where r is the radius and l is the slant height (the hypotenuse in this case).
Using the given information, the surface area of the cone can be calculated as:
Surface Area = 3.14 x 6(6 + 11) = 3.14 x 6 x 17 = 321.84
Rounding this to the nearest tenth, the surface area of the cone is approximately 321.8.
Use the image to answer the question.
A cone shows a radius of 6 and hypotenuse or side as 11.
What is the surface area of the cone? Use 3.14 for pi and round to the nearest tenth, if necessary.
