Will mark brainliest
which expression represents the surface area of the cone?

Third option

Step-by-step explanation:

By observing the diagram we can see that the diameter of circular base is 6 inches. The diameter will be sued to find the radius.

r = 6/2 = 3 inches

We can also see from the diagram that lateral height denoted by l is 5 in.

We know that the formula for surface area of a cone is given by:

Comparing it with the options we get that the third option is correct ..

The correct answer is third option

 π(3)(5) + π3²

Step-by-step explanation:

Points to remember

Surface area of cone = πrl + πr²

Where r is the radius of the cone and l is the slant height of cone

To find the correct answer

Here r = 6/2 = 3 in

l = 5 in

Surface area =  πrl + πr²

 =  π(3)(5) + π3²

The correct answer is third option

 π(3)(5) + π3²

yes
