Answer:
78.75 cm³
Step-by-step explanation:
Volume = Width × Height × Length
V = 5 × 4.5 × 3.5
V = 78.75 cm³
What you would have to do is take the 18 and double it because 50% doubled is 100% so when you double 18 it is 36
4x=9y+2
x=(9y+2)/4
11x-8=90+9y+2
11((9y+2)/4)-8=9y+92
(99y+22)/4=9y+100
99y+22=36y+400
63y=378
y=6
x=14
is the question asking for y or x？？or is it asking for angle
I hope this helps you
radius=diameter/2=22/2=11
Area =pi.r^2
Area =3,14.11^2
Area =379.94
46.06 would be the answer
