Answer:
401.92 in²
Step-by-step explanation:
S.A. = 2πr²+2πrh
S.A. = 2π4²+2π4·12
S.A. = 100.48 + 301.44
S.A. = 401.92 in²

Answer:
0.28.
Step-by-step explanation:
It is given that a baseball player hit the ball 42 times out of the last 150 times at bat.
Total no of times he bat = 150
No. of times he hit the ball = 42
We need to find the player's experimental probability of getting a hit the next time at bat.
Therefore, the required probability is 0.28.
