Answer:
3/5
Step-by-step explanation:
The rule for the angle formed outside of circle by intersection show below is given by:
Angle formed outside=1/2(difference of intercepted arcs)
∠ACE=1/2(AE-BD)
∠ACE=53°
AE=233°
BD=x
Hence the formula for obtaining BD will be:
53=1/2(233-x)
The correct answer is A
Answer: 45
Step-by-step explanation:
By the tangent secant theorem we have AB^2 = BD(BD + CD)
So...
14^2 = 4(CD +4)
196 = 4CD + 16
4CD = 180
CD = 45
Reverse distribute
ab+ac=a(b+c)
find a which is GCF greates common factor
36x=2*2*3*3*x
60=2*2*3*5
gcf is 2*2=4
36x/4=9x
60/4=15
36x+60=4(9x)+4(15)=4(9x+15)
Answer:
V = 904.3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
Let pi = 3.14 and the radius is 1/2 of the diameter d= 12 so r =1/2(12) =6
V = 4/3 (3.14) * (6)^3
V = 4/3 * 3.14 * 216
V =904.32
Rounding to the nearest tenth
V = 904.3
