Question

find the surface area of the figure.
Use 3.14 for π and round to the nearest hundredth.
a. 489.84 m2
b. 263.83 m2
c. 501.86 m2
d. 376.82 m2

Answer 1

Given:

Given that the radius of the cylinder is 6 m.

The height of the cylinder is 7 m.

We need to determine the surface area of the cylinder.

Surface area of the cylinder:

The surface area of the cylinder can be determined using the formula,

$SA=2 \pi r(r+h)$

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

Substituting r = 6 and h = 7 in the above formula, we get;

$SA=2 (3.14)(6)(6+7)$

Simplifying, we get;

$SA=2 (3.14)(6)(13)$

Multiplying, we get;

$SA=489.84 \ m^2$

Thus, the surface area of the cylinder is 489.84 square meters.

Hence, Option a is the correct answer.
