I'm assuming the deck is the shaded area.
To find the area of the deck, find the area of the large circle and subtract the area of the small circle from it:
A of large circle: R = (4.2/2) + 1.7 = 3.8; area: 3.8^2 * pi is about 45.3.
A of small circle: r = 4.2/2 = 2.1; area: 2.1^2 * pi is about 13.8
Now, subtract:
45.3 - 13.8 = 31.5 meters squared
I'm getting 40.9 but double check, (<span>π x r^2) x height?</span>
Answer:
Each dice has six combinations which are independent. Therefore the number of possible outcomes will be 6*6 = 36. The probability of rolling a pair of dice whose numbers add to 5 is 4/36 = 1/9.
Step-by-step explanation:
For the odds of these two numbers coming up at the same time, you multiply the odds of one times the odds of the other. 5/6 × 1/6 = 5/36. So the odds that you'll roll 2 dice total six are 5/36 each time you roll ( or approximately 1 chance in 7).
Well, that would be 4 tables to fit 20 people but would not be enough for 2 more people so I would say 5 tables total.
