The surface area of a spherical dome can be calculated with the formula 2πrh, where r is the radius of the base of the dome and h is the height of the dome.

In the first option, 60π m2 represents a case where 2πrh=60. Given the physical reality of a spherical dome, this would correspond to fairly small values for both r and h.

Option 2 gives a surface area of 109π m2 which means 2πrh=109. This represents a dome that is larger than in option 1.

Option 3 shows a surface area of 120 π m2, meaning 2πrh=120. The dome here is even larger than in option 2.

Lastly, option 4 suggests a surface area of 300π m2 where 2πrh=300. This is the largest dome of all the options.

Given these explanations, without values for r or h we can not definitively say which option is correct. But, if the correct answer given is option 2, it suggests that the value of 2πrh for the given sphere is 109.
