The diameter of the circle is needed. But to solve, you would simply multiply the diameter of the circle by pi (3.14).
Answer:
0.99, 1.45 then 2.56 will be the greatest!
Answer:
Step-by-step explanation:
First distribute. -2•x and -2•3
This will give you y-4=-2x+-6
(You could also write it y-4=-2x-6)
Then add 4 to both sides.
y=-2x-2
Answer:
i. <DCB = 
ii. Sin of <DCB = 0.8
Step-by-step explanation:
Let <DCB be represented by θ, so that;
Sin θ = 
Thus from the given diagram, we have;
Sin θ = 
= 0.8
This implies that,
θ =
0.8
= 53.1301
θ = 
Therefore, <DCB =
.
So that,
Sin of <DCB = Sin 
= 0.8
Sin of <DCB = 0.8
-5.1=1.3+w/4
Subtract 1.3 from both sides
-6.4=w/4
Multiply both sides by 4
-25.6=w
Check work:
-5.1=1.3+(-25.6/4)
-5.1=1.3+(-6.4)
-5.1=1.3-6.4
-5.1=-5.1
Hope this helps! :)
