Answer:
1. 17.59
2. 81.68
3. 8.99225
4. 12.00028
Step-by-step explanation:
for the first two you have to multiply the radii by 2 to find the diameter, then multiply your diameter by pi (3.14) to find the circumference
for the second two you have to work backwards so you have to divide the circumference by pi (3.14) which will give you the diameter, then you have to divide the diameter by 2 to get the radius.
Someone else on Brainly had the same question, he showed the work so I copied it so you can see it.
We have 48 meters.
We need to increase it by 20%.
That means we have 48 and then we increase it by 20%.
That can be expressed as:
48 + (48 * 20%)
Now, another way to write that would be:
48 * 120%
Now, 120% is nothing but 120/100. This can even be simplified to 1.2.
48 * 120%
= 48 * 1.2
= 57.6
48m increased by 20% is 57.6m<span>.</span>
The center of the circle is (3,9) so the answer is A
False. It’s should be 3/4
Answer:
4/663
Step-by-step explanation:
There are 4 queens and 4 kings in a deck. Drawing a queen would be 4/52. Drawing a king afterwards with replacing the queen would be 4/51 because you took a queen but didn't replace that one queen card so the deck has only 51 cards left after you drew the queen. Drawing a queen would not affect your chance of drawing a king card, it will only affect the total number of cards left because you didn't replace the card afterwards. 4*4=16;52*51=2652. 16/2652 can be simplified to 4/663 by dividing 4 to both numbers. 16/4=4 and 2652/4=663. The probability of drawing a queen then a king without replacement would be 4/663.
