Answer:

surface area (rounded to the nearest tenth) : 282.7 yd²

Step-by-step explanation:

Formula ……………………………………………………………

surface area of a cylinder = 2 × (area of the base) + the lateral surface area

= 2πr² + 2πrh

= 2πr(r + h)

==================================

surface area of a cylinder = 2×π×3×(3+12)

= 282.743339 yd²
