Answer:
half of 20 is 10
10 is your new radius so
10^2 = 100
100 x 3.14 = 314
Now we multiply by the height:
314 x 11 = 3,454 cm^3
The area is 297 because...
8 times 8.25 times 4.5 is equal to 297
The comparison of the lengths of the sides based on the angles are given
by sine rule.
The lengths of the sides from greatest to least are;
Reasons:
The given parameters are;
∠A = 78°, ∠B = 56°, ∠C = 46°
By sine rule, we have;

Given that, sin(46°) ≈ 0.719, sin(56°) ≈ 0.829, sin(78°) ≈ 0.978, we have;
sin(78°) > sin(56°) > sin(46°)
Therefore, applying equal proportions of similar ratios, we have;
<u>BC > AC > AB</u>

Answer:
c
Step-by-step explanation:
the graph shows that becky started at ten dollars and everyday it goes down by 3 so c is the correct answer
Median=85 since it is the middle data point
Q1= 80 because it is the middle of the left side of the median
Q3=90 since it is the middle of the right side of the median
IQR= Q3-Q1=90-80=10
