1834 bfc I believe that’s the right answer
A circular pool with a diameter of 18 ft will have a uniform
4 ft concrete walkway poured around it. If the concrete cost $4.25 a square
foot, how much will it cost for the concrete?
This can be solve be solving the area of walkway
Area of walkway is equal to = (pi)( 9 ft +4) ^2– (pi)(9ft)^2
= 276.46 sq ft
Cost = 276.46 sq ft * ($4.25 a square foot) = $1174.70
-0.85, 0.25, 60, 60 2/40
hope this helps! :)
Answer:
C
Step-by-step explanation:
Definition: Two events, A and B, are independent if the fact that A occurs does not affect the probability of B occurring.
Event A = getting a 4 on the first roll.
Event B = getting a 4 on the second roll.
True option C: A and B are independent events, because the probability of the first roll will not affect the probability of the second roll.
