The ratio of base radius to slant height of a right circular cone is 4:3. Calculate the ratio of the total surface of the cone to the curved surface of the cone.(Take pi= $\frac{22}{7}$ )

Open in App

Solution

Total surface of cone= π r(l+r)

Curved Surface area of the cone= πrl

Their ratio=1+ $\frac{r}{l}$ =7:3
