Question

From a right circular cylinder of radius 10 cm and height 21 cm a right circular cone of same base radius is removed. If the volume of the remaining portion is 4400 cm^3 , then the height of the cone removed is

Answer · 0 votes

Let the height of cone be 'h', then pir^2H = 13pir^2h = 4400cm3 pir^2 [ 21 - h3 ] = 4400 63 - h = 3 × 4400 × 722 × 10 × 10 = 42 h = 63 - 42 = 21cm

Answer 2

Answer:

The volume of a right circular cone can be found using the formula: V = (1/3) * pi * r^2 * h, where r is the radius and h is the height.

The answer is: 7241.75 cm^3

Step-by-step explanation:

A right circular cone is a geometric shape that is defined by a circle at one end (the base) and a straight line (the axis) that extends upward from the center of the base to a point (the vertex or apex), not on the base.

The base and the vertex are always in the same plane, and the axis is always perpendicular to that plane.

The line segment from the vertex to the center of the base is the height of the cone, and the distance from the center of the base to the edge of the base is the radius of the cone. It is called "right" because the vertex is directly above the center of the base. Thus, the angle between the axis and the base is 90 degrees.

So, the volume of a right circular cone with a radius of 10.5 cm and height of 21 cm is:

(1/3) * pi * (10.5 cm)^2 * (21 cm) = (1/3) * 3.14 * 110.25 * 21 = 7241.75 cm^3
