Question

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

Answer 1

Answer:

Option A is correct

703.36 square inches.

Step-by-step explanation:

Surface area(A) of cylinder is given by:

$A=2\pi r (h+r)$            ....[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 $\pi = 3.14$ in [1] we have;

$A = 2 \cdot 3.14 \cdot 8 \cdot (6+8) = 50.24 \cdot 14$

Simplify:

$A = 703.36 \text{in}^2$

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