A cone is 8cm high and its vertical angle is 62 deg. find the diameter of its base |
|
Answer» The answer is approximately around 26cm. Step-by-step explanation: Height of the cone =8cm. Vertical ANGLE =62° Then angle on each side of the height I=62°/2=31°. Let the DIAMETER of the base be 2r. Tan theta =Height / base=>tan31°=8/r=>0.6=8/r =>8/0.6=r=>13.2~13. Then d=2r=2×13=26cm approximately. |
