What is the surface area of the cone? Use 3.14 for pi and round to the nearest tenth, if necessary.%0D%0A%0D%0A(1 point)%0D%0A$$ square units%0D%0ACheck Answer
To find the surface area of a cone, we need to use the formula:
Surface area = π × r × (r + l)
Where r is the radius of the base and l is the slant height of the cone.
However, since we're not given any values for r or l, we cannot calculate the surface area. Please provide the necessary information to continue.
the values are 11 and 6
Given that the radius of the base (r) is 11 units and the slant height (l) is 6 units, we can now calculate the surface area of the cone.
Surface area = π × r × (r + l)
Plugging in the values, we get:
Surface area = 3.14 × 11 × (11 + 6)
Surface area = 3.14 × 11 × 17
Surface area ≈ 588.86 square units
Rounded to the nearest tenth, the surface area of the cone is approximately 588.9 square units.
wrong
Apologies for the mistake. Let's recalculate.
Given that the radius of the base (r) is 11 units and the slant height (l) is 6 units, we can now calculate the surface area of the cone.
The surface area of a cone is given by the formula:
Surface area = π × r × (r + l)
Plugging in the values, we get:
Surface area = 3.14 × 11 × (11 + 6)
Surface area = 3.14 × 11 × 17
Surface area ≈ 590.74 square units
Rounded to the nearest tenth, the surface area of the cone is approximately 590.7 square units.
