The formula for the surface area of a cone is:
A = πr(r + l)
where A is the surface area, π is a constant approximately equal to 3.14, r is the radius of the base, and l is the slant height of the cone.
Given that the radius (r) of the cone is 6 and the slant height (l) is 11, we can substitute these values into the formula to find the surface area.
A = 3.14 * 6(6 + 11)
A = 3.14 * 6(17)
A = 3.14 * 102
A ≈ 319.88
Rounded to the nearest tenth, the surface area of the cone is approximately 319.9 square units.
What is the surface area of the cone use 3.14 for pi and round to the nearest tenth and necessary 6 and 11
