A) C/6.5
B) 6.5/C
C) C/13
D) 13/C
Answer:
C) C/13
Step-by-step explanation:
The circumference of a circle is given by the formula
C = pi * d where c = circumference and d is the diameter
The diameter is 13
C = pi *13
Divide each side by 13
C/13 = d
The diameter is C/13
Circumference of the circle is the length of the boundary of the circle. The expression best represents the value of pi is C/13.
Given-
The circumference of the given circle is C centimetres.
Diameter of the given circle is 13 centimetres.
Circumference of the circle is the length of the boundary of the circle.
We know that the circumference of the circle is given by,
Here r is the radius of the circle. Radius is the twice the diameter of the circle of the circle. That is,
put the value in the parameter of the circle we get.
The value of circumference is C cm and diameter is 13 cm. Put these values to solve it further,
Rewrite the equation for the pi, we get,
Hence, the expression best represents the value of pi is C/13.

The image is a rectangle that says 6 then a smaller rectangle that says 1.5
Answer:
The answer is 0.25! :)
Step-by-step explanation:
To find the scale factor, you have to do division of the shorter sides of the first and second rectangle. 1.5/6 which equals 0.25.

Answer:
Its d 6
Step-by-step explanation:
Answer:
1. Simply the left hand side by first multiplying the -12 with the (1-x) to get -12+12x since negative×negative will give you positive. So after the simplification on the left hand side you will get the expression 10-12+12x. Which will give you -2+12x on the left hand side.
2. You do same on the right hand side of the expression 8(-12+6x) -14. So you multiply the 8 with the expression in the bracket ONLY (-12+6x) then afterwards,you add the -14 it to get -96+48x-14 =-110+48x .NOTE. ADDING TO NEGATIVE NUMBERS GIVES YOU A NEGATIVE ANSWER. so -96+(-14)=-110. So after simplification. You will also get the expression-110+48x on the right hand side .
3. Then combining the two sides of the equation, the whole expression becomes
-2+12x = -110+48x. Then you group like terms by sending all number attached with a variable to the right hand side and non attached variable numbers to the left , given you
-2+110 = 48x-12x . NB .WHEN A POSITIVE NUMBER CROSSES THE EQUAL SIGN IT CHANGES TO NEGATIVE AND VICE VERSA.
4. -2+110 = 108 and 48x -12x =36x
So the final expression becomes 108= 36x
Then you divide both side by 36 ,thus 108÷36=36x÷36
Given you x= 3 as your final answer of the expression, since 108÷ 36= 3. And 36x÷36= x
