Answer:
<h2>
234</h2><h2>
</h2>
Step-by-step explanation:
surface area = 2( LW + LH + WH)
where L = Length = 9
W = Width = 2
H = Height = 9
<u>plugin values into the formula:</u>
surface area = 2 ( LW + LH + WH)
= 2 ( 9*2 + 9*9 + 2*9 )
= 2 ( 18 + 81 + 18 )
= 2 (117)
= 234

Answer:
<em>Diameter= 11.27 feet</em>
Step-by-step explanation:
<em>Circle = 2πr</em>
<em>or, 11.27π = 2πr</em>
<em>or, 11.27π/2π = r</em>
<em>r = 5.635 ft</em>
<em>diameter = 2r</em>
<em>= 2 x 5.635</em>
<em>= 11.27 feet</em>
Your answer is 40mm
