Cylinders
A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.
Cones
A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is drawn by joining the apex to all points on the base, using segments, lines, or half-lines, provided that the apex and the base both are in different planes.
in a frustum of a right circular cone, the diameter of the lower base is 24 ft, while the diameter of the upperbase is 14ft. if the slant height of the frustum is 13 ft, find the total area of the frustum.
A. 1,382 sq.ft
B. 1,385 sq.ft
C. 1,389 sq.ft
D. 1,387 sq,ft
