Answer:
38π
Step-by-step explanation:
circumference= 2πr= 2×π×19=38π
96 in total since 3 times 12 equals 36. Then you have 4 times 12 which equals 48. Also you have 2 times 6 equals 12. THEN you add it together to get 96.

Answer:
8/13
Step-by-step explanation:
There are total 26 red cards in the deck of 52 cards.
There are also 12 face cards in the deck ( which is 6 of them are red, while 6 of them are black)
Since we only need either one of them, 26 + 6 = 32
The probability of drawn a card that either red or a face card is 32/52
The simplest form of this fraction is 8/13.
