Find the surface area of the following cylinder in cubic inches.

a. 703.36 in.2
b. 351.68 in.2
c. 401.92 in.2
d. 427.04 in.2

Option A is correct

703.36 square inches.

Step-by-step explanation:

Surface area(A) of cylinder is given by:

           ....[1]

where,

r is the radius of the cylinder and h is the height of the cylinder.

As per the statement:

From the given figure:

h = 0.5 ft and r = 8 inches.

Convert ft into inches.

1 ft  = 12 inches

then

in 0.5 ft = inches

Substitute the given values and use in [1] we have;

Simplify:

Therefore, the surface area of the following cylinder is, 703.36 square inches.
