Given:
R = h = 3cm
Vcone -?
Decision:
The volume of the cone is calculated by the formula:
V = 1/3 * P * R ^ 2 * h,
P = 3.14 (constant),
according to the conditions of the problem, the radius of the base is equal to the height of the cone, which means R = h = 3cm.
Substitute the numbers:
V = 1/3 * 3.14 * 3 ^ 2 * 2 = 28.26cm ^ 3
Answer: 28.26 cm ^ 3 is the volume of the cone.
