Answer:
The area of the circle is 314 inches
Step-by-step explanation:
Area if a circle = πr²
r = radius
r= d/2
r=20 /2
r=10 inches
Area =3.14×10²
= 3.14×100
=314 inches
38 because 80% of 20 is 18 and then add the 2
$70
Multiply 14×5 for the answer beacuse
1 ticket=14, so 5 tickets would be $70
13 years
Step-by-step explanation:
17 + 15 + 23 + 23 + 23 =101 / 5 = 20.2
Mean before was 20.2
In order for the mean to be 19, all those numbers would have to add up 114 to be divided by 6 and have a mean of 19
114 / 6 = 19
114-101 = 13 is that number
17 + 15 + 23 + 23 + 23 + 13 = 114 / 6 = 19
