what is the lateral area of a cone with radius 19 cm and slant height 11cm
The lateral area of a cone is given by the formula L = πrl, where r is the radius and l is the slant height.
In this case, r = 19 cm and l = 11 cm. Therefore, we have:
L = π(19)(11) ≈ 658.5 cm^2
So the lateral area of the cone is approximately 658.5 square centimeters.
