What is the perimeter of triangle ABC?
2 answers:
Answer:
The perimeter of triangle ABC is 30 units.
Step-by-step explanation:
Given information: AC, CB and BA are tangents.
According to the property of tangents from the same external point, the tangent segments to a circle are equal.
Using this property we can say that
The perimeter of triangle ABC is
Therefore the perimeter of triangle ABC is 30 units.

Answer:
300π cubit units
Step-by-step explanation:
See attached image for oblique cylinder diagram.
The volume is given by the formula:
V = Area of Base * Height
The base is a circle with area formula πr^2 where radius is shown as 5
So
Area of Base = πr^2 = π(5)^2 = 25π
And, height is given as 12
So
Volume = Area of Base * Height = 25π * 12 = 300π cubit units
Answer:
0.3333 = 33.33% probability that this red ball is from box A.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Red ball
Event B: From box A.
Probability of a red ball:
3/10 = 0.3 of 1/2 = 0.5(box A)
6/10 = 0.6 of 1/2 = 0.5(box B). So
Probability of a red ball from box A:
0.3 of 0.5, so:
What is the probability that this red ball is from box A?
0.3333 = 33.33% probability that this red ball is from box A.
