Answer 1

The answer is 99 your welcome

Answer 2

Answer:

≈1130.97336 yd

Step-by-step explanation:

the formula to find the surface is A= 2 π r h + 2 π r 2

where r is the radius and h the height. you subsitute it with your value.

r = 9 yd and h = 11 yd

so, A= 2 π r h + 2 π r 2 = 2 x π x 9 x 11 + 2 x π x 9^2 ≈ 1130.97336 yd
