A cylinder is a tree-dimensional figure with two parallel bases bounded by congruent circles and a curved lateral surface that connects the circles. The height, h, of a cylinder is the length of any perpendicular segment drawn from a point on the base to the plane containing the other base. A cylinder is a right cylinder if the segment joining the centers of the bases is perpendicular to the planes of the bases. Otherwise, the cylinder is oblique.
If a right cylinder has a height h and a base with radius r, then the lateral area L.A. is given by the formula: L.A. = 2(pi)(r)(h)
The surface area S.A. is given by the formula: S.A. = L.A. + 2(pi)(r^2).
Thus, the area of the cylinder's base is (pi)(r^2).

How do you find the surface area of a right cylinder?
The surface area formula for cylinders and prisms is SA = 2B + l where B is the area of your base l is your lateral area which is equal to l=ph where p is the perimeter (or circumference in your case) of the base and h is the altitude All cylinders have circular bases so the base area b = pi * r^2 where r is the radius of the circle the formula for circumference is 2*pi*r, where r is again the radius So, l = 2*pi*r*h And finally SA = 2*pi*r^2 + 2*pi*r*h This can be simplified to SA = 2*pi*r*(r+h)
The volume of a cylinder with a base of radius r is the area of the base times the length of its altitude h Which of the following is the formula for the volume of a cylinder?
v=pi.r^2h
What is the formula for a sphere?
Surface Area=4/3*pi*r2 Where r=radius Volume= 4*pi*r3 Where r=radius There are NO equations for the area or the lateral area
How do you caculate the volume of a cylinder?
Volume of a CylinderThe volume of a cylinder is the product of the area of its base and its height. Because a cylinder has a circular base, the volume of a cylinder is: Pi x r squared x hwhere r is the radius of the circular base and his the height.
How do you calculate this a right circular cone is inscribed in a hemisphere so that base of cone coincides with base of hemisphere what is the ratio of the height of cone to radius of hemisphere?
Suppose the radius of the sphere is R. The base of the cone is the same as the base of the hemisphere so the radius of the base of the cone is also R. The apex of the cone is on the surface of the hemisphere above the centre of the base. That is, it is at the "North pole" position. So the height of the cone is also the radius of the sphere = R. So the ratio is 1.
