Answer:20 cm
Step-by-step explanation:
Volume of cone=540π
Radius=r=9
Volume of cone=1/3 x π x r^2 x h
540π=1/3 x π x 9^2 x h
540π=1/3 x π x 9 x 9 x h
540π=(1xπx9x9xh)/3
540π=(81πh)/3
540π=27πh
Divide both sides by 27π
540π/27π=(27πh)/27π
20=h
h=20
Height =20 cm

The probability of getting a black king of hearts is 1/52
From the question, we have:
The number of cards in a standard deck, n = 52
Black king of heart, r = 1
The probability of getting a black king of hearts is the quotient of the number of black king of heart and the total number of cards in the deck.
So, we have:
p = 1/52
Hence, the probability of getting a black king of hearts is 1/52
