Answer:
13.35 millimeter. (About)
Step-by-step explanation:
To find the area or circumference of any circle, you need to use pi. So, if we are trying to fine the area of a <em>semicircle, </em>you use the the formula:
πr²/2
So, if the radius is 8.5,
8.5 · 3.14 = 26.69
Now we divide it by 2.
26.69 = 13.345
Since the question is asking to round to the hundredths, the answer will be 13.35 millimeters.
31.4 is the circumference
Multiply the diameter by Pi
Answer:
Step-by-step explanation:
Table 1
3:5 , 6 : 10 , 9 :15 , 12 : 20
Table 2
7 : 10 , 14 : 20 , 21 : 30 , 28 : 40
All table 1 Ratios are equal
All table 2 Ratios are equal
3 : 5
= 6 : 10
6 < 7
=> 6 : 10 < 7 : 10
=> 3 : 5 < 7 : 10
=> The ratio 3:5 is less than the ratio 7:10
All table 1 Ratios are equal
All table 2 Ratios are equal
=> All table 1 Ratios are less than the ratios in Table 2
The ratio 14:20 is greater than the ratio 9:15.

Y = mx + b
y = 3/5(x) + b
-4 = 3/5(2) + b
-4 = -2.4 + b
b = -4 + 2.4
b = -1.6 (-8/5)
y = 3/5x - 8/5.
