Answer:
52 x 7= 50 x 7 + 2 x 7
Step-by-step explanation:
Answer:
Circumfrence: 40.21
Radius: 6.4
Step-by-step explanation:
For radius, you only have to divide the diameter (in this case 12.8) by 2 which gives us 6.4
For Circumference, plug in the radius in the formula C=2π(6.4), and that gives us 40.21
The expression with the smallest value is D
<u>Answer</u>:
The length of the rectangle is 70 cm
The width of the rectangle is 32 cm
Step-by-step explanation:
<u>Given:</u>
perimeter of the rectangle = 204 feet
Its length is six feet longer that twice its width
<u>To Find:</u>
The dimensions of the rectangle = ?
<u>Solution:</u>
Let the width of the rectangle be x
Then its length is six feet longer that twice its width.
That is length = 6 + 2x
Now we know that the perimeter of the rectangle is
perimeter = 2(length + width)
204 = 2(6+2x+x)
204 = 2(6+3x)
204 = 12 +6x
204 - 12 = 6x
192 = 6x
x =
x = 32
Thus the width is 32 cm
Its length is
=6 + 2x
=6 + 2(32)
=6 + 64
= 70 cm
