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.

The triangles in the diagram are congruent. if mzf = 40°, mza = 80°, and mzg = 60°, what is mzb?

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
