V = 827.02 
Step-by-step explanation:
height ( <em>h </em>) = 13 mm
radius ( <em>r </em>) =
= 4.5 mm
Surface area = 
= 2π(4.5)(13) + 2π(4.5)
≈ 494.80 
Volume = 
<em> </em>= 
= 827.02 
Answer:
a)16 (2*2*2*2= 16)
b)16 (-4*-4-16)(-+-=+)
c)500 (5*5*5=125 125*4=500)
d)0.49 (0.7*07)
e)480 (4^=16 9^=81 121^0=1 16+81 -1 =96 96*5=480)
f)5^2 or 25 (a^m/ a^n=a^m-n)
g) 11^14 (reason same as the f one)
h)8.20
i) 4(-4*16=64)
j)900
