Answer:

24.8 inches

Step-by-step explanation:

Volume of a cylinder=πr²h

Where volume=774 and h=0.4

Now

774=(3.14)r²(0.4)

774=1.2566r²

Divide both sides by 1.2566

r²=615.94

Taking sq root on both sides

r=24.8 inches

What is the probability that the card is either a black cardblack card or aa 99​?
DerKrebs [107]
It sounds like your book is asking "what is the probability that the card is either a black card or a 9"

If so, there are 26 black cards (13 spades and 13 clubs) and four cards that have "9" on them (one in each suit). We have 26+4 = 30 cards that are either one or the other. There is overlap though. Namely the 2 black cards that have "9" on them (we count them twice), so we should subtract to get 30-2 = 28

There are 28 cards that either have a '9' on them, they are black, or both

This is out of 52 cards total

Divide the two values: 28/52 = 14/26 = 7/13 = 0.53846

Answer as a fraction: 7/13
Answer in decimal form: 0.53846
Answer as a percentage: 53.846%
Side note: the decimal form and percentage form are approximate
