(Remember i only do 8th grade assignments sorry if your younger or older)
In order to check if these surface area calculations for cones are correct, we need to know the dimensions of the cones (radius and slant height or height) for each problem. The formula for the surface area of a cone is given by:
Surface Area of a Cone = πr(r + l)
where r is the radius of the base of the cone and l is the slant height.
Without the dimensions of the cones, I cannot verify the accuracy of the surface areas you've provided.
If you can supply the dimensions of the cones for each of these surface area values, I can then confirm whether they are correct or incorrect.
