A right circular cone has a circular base and its axis is perpendicular to the base at the centre point. Learn in detail area and volume formulas along with solved examples at BYJU’S.
The surface are a of a right-circular cone of radius r and height h isS=πr√(r^2+h^2),andit volume is V = fπr2h. Determine the ratio h/r for the cone with given surface are a S and maximum volume V. 相关知识点:
- h is the height of the cone (24 cm),- r is the radius of the base (7 cm). Substituting the values:l=√242+72l=√576+49l=√625l=25 cm Step 2: Calculate the curved surface area (CSA) of the coneThe formula for the curved surface area of a cone is:CSA=πrlUsing π=227...
