Circumference of a circle: 2 * Pi * R
1. Calculate radius from diameter.
Radius = Diameter/2
Radius = 15/2
Radius = 7.5cm
Formula to calculate the circumference:
2 * Pi * R
= 2 * Pi * 7.5
= 15 * Pi
= About 47.10 cm in terms of Pi.
So, in conclusion, the circumference if this circle is about: 47.10cm.
For the table 0.2 would be (1/5) 0.5 would be (1/2). And 0.7 would be (7/10).
For number 2 I would say the denominator changed each time
Hey there!!
(1) Both the angles sum up to be 180.
(2) Both the angles sum up to be 90
_________________
(1) 4x+5+8x-5=180
... 12x=180
... x= 180/12
... x = 15
________________
(2) 4z+3z+6=90
... 7z+6=90
... 7z=84
... z=84/7
... x=12
