16. A cone has a surface area of 16πm2 and a volume of 8πm3. If a similar cone has a surface area of 100πm2. What is the similarity ratio of the smaller cone to the larger cone? What is the volume of the larger cone?
Q. 16. A cone has a surface area of 16πm2 and a volume of 8πm3. If a similar cone has a surface area of 100πm2. What is the similarity ratio of the smaller cone to the larger cone? What is the volume of the larger cone?
Calculate Scale Factor: Calculate the scale factor for the surface areas of the cones. Given surface area of smaller cone = 16πm2, surface area of larger cone = 100πm2. Scale factor squared = (Surface area of larger cone) / (Surface area of smaller cone) = (100π)/(16π)=6.25. Scale factor = 6.25=2.5.
Calculate Volume: Calculate the volume of the larger cone using the scale factor.Volume of smaller cone = 8πm3.Volume of larger cone = (Scale factor)3 * (Volume of smaller cone) = 2.53∗8π=15.625∗8π=125πm3.
