Question 1206648: a) The area of a sector of a circle with diameter 12cm is 6.6cm², if the sector is folded to form a cone,
Calculate the radius of the base of the cone.
b) A sector of angle 65° is removed to form a thin circular sheet of radius 15cm and folded to form a right circular cone. Calculate the volume of the cone
You can put this solution on YOUR website! ) The area of a sector of a circle with diameter 12cm is 6.6cm², if the sector is folded to form a cone,
Calculate the radius of the base of the cone.
when folded the radius of sector becomes the slant height of the cone
The area of sector becomes the lateral surface area of cone
6.6 = pi*r*6
r (cone) 6.6/(6*pi)
= 0.35 cm
The radius of the base of the cone is approximately 0.35 cm.
ector of angle 65° is removed to form a thin circular sheet of radius 15cm and folded to form a right circular cone. Calculate the volume of the cone
