Well, we have to determinate the 65% of 140, which are 91 members play soccer.
The total members are 140, if 91 play soccer, 49 members do not play soccer.
The answer is 49 members.
1 radian = 180/pi
5 radians = x
X= 5• 180/pi
= 900/pi
= 286.6
Answer:
∠72°.
Step-by-step explanation:
If a circle has a circumference of 20 and an arc with a length of 4, we can simply set up a ratio to determine the angle of the arc in degrees:

Cross multiply:

Divide both sides by '20':
x = 72°.
Therefore, the measure of the central angle of the arc is ∠72°.
Answer:
question 2 is true
question 3 is false
Step-by-step explanation:
Answer: h=(D²-s)/3
Step-by-step explanation: D² =3h+s
Subtract a from both sides of the equation
D²-s =3h+s-s
Simplifying,
D²-s =3h
Divide both sides by 3( to isolate 'h')
(D²-s)/3 =3h/3
Simplifying,
(D²-s)/3 =h
Hence, h= (D²-s)/3
Hope it helps!
