Which statements about the surface area of a cone are true? Check all that apply. A cone is similar to a pyramid, but a cone has a circular base.
The equation for the base area of a square pyramid is the same as that for the base area of a cone.
The lateral area of the cone is One-half C l, where C represents the circumference of the base and l represents the slant height.
The slant height is the distance from any point on the circular base to the vertex.
The surface area of the cone is the product of the base area and the lateral area.

(40 points) i need some . an answer definition is appreciated as well.

Tell whether the two rates form a proportion

(01.03 mc) which of the following is a step in simplifying the expression x multiplied by y to the power of 2 over x to the power of negative 3 multiplied by y to the power of 3, the whole to the power of negative 4. select one: a. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 7 multiplied by y to the power of negative 1. b. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of 12 multiplied by y to the power of negative 12. c. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of negative 3 multiplied by y to the power of 3. d. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 3 multiplied by y to the power of 3.
