Area of a circle = circumference of a circle
πr² = 2πr
r²=2πr÷π
r²÷r=2r÷r
r=2
Answer:
It should be C: segment B prime D prime will be parallel to segment BD and will be shorter than segment BD.
Step-by-step explanation:
Step-by-step explanation:
x= how many members are in the group
x= 100/x
x= 100/(x-5)
x(x-5)=100
x^2-5x=100
x^2-5x-100=0
and then use the quadratic formula (i can't type it srry)
- 1/4 h - 1/2 + 1/2 = - 7/4
- 1/4 h = -7/4
-1 * -4
-4* -7
28:4 = 7
