Answer:
116 cm²
Step-by-step explanation:
Shaded Area = area of the larger circle - area of the smaller circle
Area of the larger circle = πr²
Where,
r = 6.5 cm
Area = π*6.5² = 42.25π cm²
Area of smaller circle = πr²
Where,
r = 2.3 cm
Area = π*2.3² = 5.29π cm²
✔️Shaded area = 42.25π - 5.29π = 36.96π = 116.113264
Area = 116 cm² (3 S.F)
Multiply 1.6 by 12 and it will give u your answer
It’s undefined because y would equal 0
From basic probability we know that if A and B are any two events in the sample space, S, then:

......(Equation 1)
In the question we have been given all the data that is required. Thus, we have: P(A)=2/3, P(B)= 4/5 and P(A U B) = 3/5.
Substituting these values in (Equation 1) we get:

This matches Option B. Therefore, Option B is the correct answer.
