Since the diameter is 12cm, we will use the radius formula = d/2= r
12/2 = 6cm
Area:
A = 3.14(r)^2
A = 3.14(6)^2
A = 3.14(36)
Answer:
A= 113.04 sq cm
Answer:
The length is of 59 cm.
Step-by-step explanation:
Perimeter of a rectangle:
The perimeter of a rectangle with width w and length l is given by:
Width of 49 centimeters and a perimeter of 216 centimeters:
This means that 
The length is cm.
We have to solve the equation for l. So
The length is of 59 cm.
49. 100-36= how many girls in percent
= 64%
64%= 16 girls
64/100=16/x
cross multiply
1600=64x
x=25
Answer:
it's too blurryyyyyyyyyyyyyyyyyyyyy
Multiply 2x-5y= -21 by 3 to make it 6x-15y= -63
Multiply 3x-3y= -18 by -5 to make it -15x+15y=90
This cancels the y’s out which leaves us with
6x=-63
&
-15x=90
x for 6x=-63 equals - 10.5 so x is - 10.5 and for -15x=90, x= -6
Then you plug in x into any equation you’d like to find y.
Let’s plug in - 10.5 into 6x... equation.
6(- 10.5)-15y=-63
63-15y= -63
-63 -63
-15y=0
y=0 and x= - 10.5. When you plug in this values it makes the equation true!
But the correct answer is the first one north. Sorry if I’m doing too much hahah
If I’m confusing here’s the right answer...
6x-15y= -63
-15x+15y=90
