Find the total surface area (in sq.cm) of a right circular cylinder of diameter 21 cm and height 10 cm.
The radii of the two circular faces of the frustum of a cone of height 21 cm are 5 cm and 3 cm. What is its volume in cub.cm
The diameter of a sphere is twice the diameter of another sphere. The curved surface area of the first and the volume of the second are numerically equal. The numerical value of the radius of the first sphere is
What happens to the volume (V) of the cuboid. if its length is doubled. height is doubled and breadth is kept the same?
Find the area and circumference of a circle if the radius is 14 cm. (Take pi = 22/7)
Find the curved surface area (in cm2) of a right circular cylinder of diameter 21 cm and height 10 cm.
The length, breadth and height of a cuboidal box are in the ratio 7 : 5 : 3 and its whole surface area is 27832 sq.cm. Its volume is:
Find the total surface area (in cm2) of a right circular cone of diameter 28 cm and slant height 12 cm.
If the edge of a cube is increased by 4 cm, the volume will increase by 988 . Then the original length of each edge of the cube is
