The regular quadrangular prism has a base edge a = 7.1 cm and a side edge of 18.2 cm long. The radius of the bottom of the cylinder is 10 cm. Determine the volume of the regular triangular prism inscribed in the cylinder. The shell of the rotating cylinder is four times larger than the contents of its base. Calculate surface area and volume of the cylinder.Ĭalculate the surface area and volume of a regular nine-sided pyramid if the radius of the circle inscribed in the base measures ρ = 12 cm and the height of the pyramid is 24 cm The height of the cylinder is 5 cm shorter than the radius of the base. The area of the cylinder surface and the cylinder jacket are in the ratio 3: 5. Please sketch the picture.Ĭalculate the surface area of a regular hexagonal pyramid with a base inscribed in a circle with a radius of 8 cm and a height of 20 cm. Please calculate the surface of a regular hexagonal pyramid with a base inscribed in a circle with a radius of 8 cm and a height of 20 cm. Calculate the volume and surface area of the pyramid. The height of a regular pentagonal pyramid is as long as the edge of the base, 20 cm. Find the volume of the pyramid to be 2.5 m high. The base of the regular pyramid is a hexagon, which can be described as a circle with a radius of 1 m. The radius of the circle circumscribed by the base is 8 cm. The regular hexagonal prism is 2 cm high.
