Answer:
315 yd
Explanation:
CYLINDER VOLUME: A (area) = π x r (radius) ^2
A = π (5)^2
A= 25 π
THEN
You need 5 (the radius) twice so 5^2 which equals 25
2 x π x r^2 (BUT WITH 25) → 2 x 25 π ^2
2 x π x r^2 (BUT WITH ORIGINAL RADIUS 5) → 2 x π(5)
Now multiply 25 x height →25 x 10.6 = 265
2 x 25 π ^2 + 265
2 x 25 = 50 + 265 = 315 π ^2
