Answer:

17 1/2 π cm²​

Explanation:

The formula for the surface area of a cylinder is:

A = 2πr^2 + 2πrh

where r is the radius and h is the height.

Given that the radius is 1 3/4, we can convert it to an improper fraction:

1 3/4 = 7/4

Similarly, the height 3 1/4 can be converted to an improper fraction:

3 1/4 = 13/4

Now we can substitute the values into the formula:

A = 2π(7/4)^2 + 2π(7/4)(13/4)

A = 2π(49/16) + 2π(91/16)

A = (98π/16) + (182π/16)

A = (280π/16)

A = 35/2 π

in mixed fraction

A=17 1/2 π cm²​

Therefore, the exact surface area of the cylinder in terms of π is 17 1/2 π cm²​.
