Q. A cylinder and a cone have the same base and altitude. If the volume of the cone is 30 cubic inches, what is the volume of the cylinder?A. 10 cubic inchesB. 15 cubic inchesC. 30 cubic inchesD. 60 cubic inchesE. 90 cubic inches
Identify Formula: Identify the formula for the volume of a cone.Volume of a cone = (31)×base area×height
Express Volume: Given that the volume of the cone is 30 cubic inches, we can express this as:30=31×base area×height
Calculate Cylinder Volume: To find the volume of the cylinder with the same base and altitude, we use the formula for the volume of a cylinder:Volume of a cylinder = base area × height
Deduce Volume Relationship: Since the base and height are the same for both the cone and the cylinder, we can deduce that the volume of the cylinder is three times the volume of the cone because the cone's volume is one third of the cylinder's volume.
Calculate Cylinder Volume: Calculate the volume of the cylinder using the volume of the cone:Volume of the cylinder = 3× Volume of the coneVolume of the cylinder = 3×30 cubic inchesVolume of the cylinder = 90 cubic inches
