What is the surface area of the cone? Use 3.14 for pi and round to the nearest tenth, if necessary. (1 point)
Radius = 6
Slat Hieght = 11
there isn't a hieght shwon
To calculate the surface area of a cone, we need to know the slant height and the radius. The slant height is the distance from the tip of the cone to any point on the circumference of the base.
Surface area of a cone = πr(r + l), where r is the radius and l is the slant height.
Given:
Radius (r) = 6
Slant height (l) = 11
Surface area of the cone = 3.14 * 6(6 + 11)
Surface area of the cone = 3.14 * 6(17)
Surface area of the cone = 3.14 * 102
Surface area of the cone = 320.68
Rounding to the nearest tenth, the surface area of the cone is 320.7.
