Answer:
see below
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius is 9 and the height is 20
V = pi ( 9)^2 ( 20)
V = 1620 pi
If we approximate pi by 3.14
V =5086.80 cm^3
If we approximate pi by pi button
V =5089.3800099 cm^3
A = 4(187*230/2) + 230²
A = 4*21505 + 230²
A = 86 020 + 52 900
A = 138 920 m²
Hope this helps !

If you need g/mL then just divide
0.3065g/138.03mL=0.002 g/mL
<span>y=2(x-3x^2+1) and if it's a multiple choice I'd also choose </span>y=1/2x^2-13x+4
A ratio compares two quantities.
penguins = 8
whales = 4
8:4 , now simplify
8/4 = 2
4/4 = 1
2:1 is the ratio.
Final answer: 2:1
