A=

Explanation:

We have given power =40 W but only 10% of this power is used so actual power

We know that from Stefan's law where is Boltzmann constant which value is

So

Given the two similar solids as shown in the diagram:

a. Volume of Solid B =

b. Surface Area of Solid A =

Given that the two solids, A and B, are similar, therefore, assuming they have a pair of corresponding dimension, given as, a and b respectively, thus:

(ratio of their volume to their corresponding sides) (ratio of their surface area to their corresponding sides)

Thus:

a. Volume of Solid A =

a = 3 cm

b = 6 cm

Substitute

a. Area of Solid B =

a = 3 cm

b = 6 cm

Substitute

Therefore, given the two similar solids as shown in the diagram:

a. Volume of Solid B =

b. Surface Area of Solid A =

Explanation:

This question has missing diagram, but I'll try to help you either way. We know that the surface area of a sphere is given by:

On the other hand, the volume of a sphere is given by:

1. The hemisphere has a total surface area of:

The total surface area of the hemisphere is half the surface area of a sphere plus the area of the base of the hemisphere which is a circular base with radius r, in other words:

2. The hemisphere has a volume of kn cm^3 . Find the value of k.

As I understand this question we want to know what is the value of k given the volume of a sphere, in other words, the volume of a sphere is:

And the volume of a hemisphere is:

So the hemisphere has a volume:

In other words:
