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
