Answer:
The internal diameter of the sphere is 6 cm.
Step-by-step explanation:
Given that, a solid right circular cone of diameter 14 cm and height 8 cm.
The radius of the cone is 

= 7 cm.
The volume of the cone is 

Let the internal radius of the sphere be r.
The external diameter of the sphere is = 10 cm
The external radius of the sphere is(R) = 5 cm
The volume of the sphere is 

The sphere is formed by the solid right circular cone.
∴The volume of the sphere = The volume of the cone
According to the problem,






⇒r= 3
The internal radius of the sphere is = 3 cm.
The internal diameter of the given sphere is = (2×3) cm =6 cm.
Step-by-step explanation:
The equation of the line is y = 4x - 9.

Answer:
54 square feet
Step-by-step explanation:
We need to find the area of the surface touching the floor and deduct it from the total surface area of the block.
The surface area of the entire block is given as:
A = 2(lw + lh + wh)
where l = length
w = width
h = height
The dimensions of the block are 2 feet by 3 feet by 6 feet. This means that:
l = 2 feet, h = 3 feet, w = 6 feet
Therefore, the total surface area is:
A = 2[(2 * 3) + (2 * 6) + (3 * 6)]
A = 2(6 + 12 + 18)
A = 2(36)
A = 72 square feet
The area of the surface that does not need covering is:
A = 3 * 6 = 18 square feet
The surface area of the part of the block that needs covering is therefore:
A = 72 - 18 = 54 square feet
