A solid right circular cone of diameter 14cm and height 8cm is melted to form a hollow sphere. If the external diameter of the s

Pani-rosa [81]

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 $=\frac{diameter}{2}$

$=\frac{14}{2} \ cm$

= 7 cm.

The volume of the cone is $= \frac13 \pi r^2 h$

$=(\frac1 3\times \pi \times 7^2\times 8) \ cm^3$

$=\frac{392}{3}\pi \ cm^3$

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 $= \frac43 \pi(R^3-r^3)$

$=\frac43 \pi (5^3-r^3) \ cm^3$

The sphere is formed by the solid right circular cone.

∴The volume of the sphere = The volume of the cone

According to the problem,

$\frac43 \pi (5^3-r^3) =\frac{392}{3}\pi$

$\Rightarrow 4(5^3-r^3)= 392$

$\Rightarrow 5^3-r^3=\frac{392}{4}$

$\Rightarrow 5^3-r^3=98$

$\Rightarrow -r^3=98-125$

$\Rightarrow-r^3= -27$

⇒r= 3

The internal radius of the sphere is = 3 cm.

The internal diameter of the given sphere is = (2×3) cm =6 cm.

Likurg_2 [28]

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
