Answer:
A = 30.25·π^5
Step-by-step explanation:
C = 2πr
11/π = 2πr
cross-multiply:
2π²r = 11
r = 11/2π² = 5.5π²
A = πr²
A = π(5.5π²)²
A = π(5.5²)π^4
A = 30.25·π^5

Answer:
The required probability is or .
Step-by-step explanation:
Consider the provided information.
A committee of 9 members is voting on a proposal. Each member casts a yea or nay vote. On a random voting basis,
The probability of yea or nay vote is equal, =
So, we can say that
Use the formula:
Where n is the total number of trials, x is the number of successes, p is the probability of getting a success and q is the probability of failure.
We want proposal wins by a vote of 7 to 2, that means the value of x is 7.
Substitute the respective values in the above formula.
or
Hence, the required probability is or .
