A cone is a solid created of a one and also its inner ( basic ), a given point not ~ above the aircraft of the one ( vertex ) and also all the segments from the suggest to the circle.
due to the fact that the base of a cone is a circle, us substitute 2 π r for ns and π r 2 because that B where r is the radius of the basic of the cone.
So, the formula for the lateral surface area the a ideal cone is L. S. A. = π r together , whereby l is the slant elevation of the cone.
You are watching: What is the base of a cone
find the lateral surface ar area the a best cone if the radius is 4 cm and the slant height is 5 cm.
l .S .A . = π ( 4 ) ( 5 ) = 20 π ≈ 62.8 cm 2
The formula for the total surface area the a best cone is T .S .A . = π r l + π r 2 .
discover the total surface area the a appropriate cone if the radius is 6 inches and also the slant elevation is 10 inches.
T .S .A . = π ( 6 ) ( 10 ) + π ( 6 ) 2 = 60 π + 36 π = 96 π in 2 ≈ 301.59 in 2
because slant elevation is undefined for an slope cone, there room no formulas because that the areas of oblique cones. The volume of a circular cone is one-third the product the its altitude and also the area of its base. ( V = 1 3 B h ) .
uncover the volume that a cone who altitude is 15 m and whose radius is 8 m.
Therefore, the volume of the cone is around 1005.31 m 3 .
