Question

what is the surface area of this cylinder? round your answer to the nearest hundredth. 12.3 yd 17.9 yd square yards submit

Explanation:

Step1: Identify radius and height

Radius $r = 12.3$ yd, height $h = 17.9$ yd

Step2: Calculate area of two circles

$2\pi r^2 = 2 \times \pi \times (12.3)^2$
$= 2 \times \pi \times 151.29 ≈ 949.98$

Step3: Calculate lateral surface area

$2\pi r h = 2 \times \pi \times 12.3 \times 17.9$
$≈ 2 \times \pi \times 220.17 ≈ 1382.94$

Step4: Sum total surface area

$949.98 + 1382.94 ≈ 2332.92$

Answer:

2332.92
