Question

5. The volume of a right circular cone is 9856 . of the diameter
the base is 28 cm, find
(1) height of the cone​

Answer 1

Answer:

Diameter of the base of the cone = 28cm

So, its radius of base= 14 cm

Let the height of cone be "h" cm.

We know that volume of cone,

= > ⅓ πr²h = 9856

= > ⅓ × 22/7 × (14)²× h = 9856

=> h= (9856× 3 × 7) / 22× 196

=> h= 48 cm.

Step-by-step explanation:

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes
