C=2pir
area=pir^2
given
c=25.12
25.12=2pir
pi=3.14
25.12=2(3.14)r
25.12=6.28r
divide both sides by 6.25
4=r
sub into other
area=pir^2
area=pi4^2
area=16pi
area=16(3.14)
area=50.24
the area is 50.24 square cm
Answer:
y = 60
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 10, then
20 = 10k ( divide both sides by 10 )
2 = k
y = 2x ← equation of variation
When x = 30, then
y = 2 × 30 = 60

Answer:
(c) x = -7
Step-by-step explanation:
An angle is equal to the sum of the angles into which it is divided.
∠MLK = ∠MLP + ∠PLK
164° = (x +31)° +(x +147)°
164 = 2x +178 . . . . . . collect terms
-14 = 2x . . . . . . . . . . . subtract 178
-7 = x . . . . . . . . . . . . . divide by 2
Answer & Step-by-step explanation:
So I can't exactly graph exactly, but I'll try...
To solve:
x+11<6 Subtract 11 on both sides.
x<-5
To graph:
<-------|---------o---------|-------->
-6 -5 -4
(The bolded part of the line is the side you shade the graph on. In case you can't see it, you have to shade the left side of the open circle.)
Hope this helps! Have an awesome day ( • ω • )^
