Answer:
a = 68°, b = 112°, c = 68°
Step-by-step explanation:
112° is a vertical angle to the one with the line through it, therefore they are equal. The angle opposite to b is equal to the one opposite to 112°. b and 112° are vertical angles, so b = 112°. a is a supplementary angle to b, so b + a = 180°. 112° + a = 180°, so a = 68°. c is vertical to a, c = 68° as well.
I hope this helps!
Answer:
7/12
Step-by-step explanation:
14/24 people have an a divide by 2 to simplify
Find volume
Vcylinder=hpir^2
volume of cylinder=(4/3)pir^3
water to height of 9
radis i3
V=9*pi*3^3
V=81pi
the balls
15 of them
diameter/2=radius
3/2=1.5
radous=1.5
15V=15(4/3)(pi)(1.5^3)
15V=20pi(3.375)
15V=67.5pi
addd tehm
81pi+67.5pi=148.5pi
aprox pi=3.14
148.5*3.14=466.29 cm^3
160.67 = 2000*8*r
So 160.67 = 16000r
Then divide 16000 on both sides 160.67/16000 =r/16000
0.01=r
