Megan picks a card from a deck of cards numbered 1-10 and rolls a number cube. What is the probability she chooses a card with a
ehidna [41]

Answer:

1/20 if there is only those 10 cards in a deck and 1/26 if there is 52 cards in the deck.

Step-by-step explanation:

There is 3/6 chances to roll a die with an even number, aka 1/2. If there are only 10 cards in the deck and only one of them has the number 5, it's 1/10. To find the probability of both these things happening, multiply the probabilities. 1/10 x 1/2 is equal to 1/20. However, since the question doesn't specify if there is 52 cards like a normal deck and 4 5's etc, there can be a different answer because if there's 52 cards in a deck, 4 of them 5's, the chance of getting a 5 is 4/52 or 1/13 and then you multiply that by 1/2 to get 1/26

Area = πr². So you have the diameter which is 56 millimeters. And the radius (r) is half the diameter, so the radius would be 28 mm. Square 28 would be 784, multiplied by π would equal 2463.00864mm. Rounded to the nearest hundredth would be 2843.01mm².
