When you have factors in shapes you must remember:
circumference and perimeter are in one unit measures
area is in squared units
volume is in cubed units
So, when the circumference of A is 4 times that of C there is a factor of 4.
Since we need to know the area the factor 4 will change to a factor of 4² since area is a squared unit.
The solution is 4²=16, the are of circle A is sixteen times the area of circle B.
Answer:
x = 9
Step-by-step explanation:
2 sides are 4 less than x, that is x - 4
The perimeter is the sum of all 3 sides, thus
x + x - 4 + x - 4 = 19, that is
3x - 8 = 19 ( add 8 to both sides )
3x = 27 ( divide both sides by 3 )
x = 9

Answer:
x = 30
Step-by-step explanation:
In the figure attached,
Two lines are parallel and one line having two adjacent angles (4x)° and (x + 30)° are the transverse.
Sum of interior consecutive angles = 180°
So the sum of these angles = 180°
(4x)° + (x + 30)° = 180°
(4x + x) + 30 = 180
5x + 30 = 180
5x = 180 - 30
5x = 150
x = 30
Therefore, value of x = 30
