The diameter and height of the bottom of a cone are 8 cm. What is its volume
It's the radius of the bottom
8 △ 2 = 4 (CM)
The volume is
4 × 4 × 3.14 × 8 × 1 / 3 = 133.97 (cm3)
The diameter of the bottom surface of a cone is 15 cm, the height is 8 cm, the volume is cubic cm, fast,
Specific formula, list out, by the way to write a conic area formula, it is best to tell me
Radius = 15 △ 2 = 7.5 (CM)
Bottom area = 3.14 × 7.5 & # 178; = 176.625 (cm2)
Volume = 176.625 × 8 △ 3 = 471 (cm3)
The volume of the cone = the area of the bottom × the height △ 3
A cone has a diameter of 8 cm at the bottom, a height of 5 cm and a volume of cubic cm
Bottom area = 3.14 × (8 △ 2) & sup2; = 50.24 square centimeter
Volume = 1 / 3 × 50.24 × 5 = 83.73 cm3
