1)To find radius diameter/2
21.5÷2=10.75
[tex]10.75 {}^{2} \times \pi = 362.87[/tex]
area =362.87cm
2)
[tex]\pi \times 13.2 {}^{2} = 547.39[/tex]
area=547.39cm
a)
Area = pie × ( 21.5 / 2 )^2
Area = pie × ( 10.75 )^2
Area = pie × 115.5625
Area = 3.14 × 115.5625
Area = 362.86625 cm^2
___________________________
b)
Area = pie × ( 13.2 )^2
Area = pie × 174.24
Area = 3.14 × 174.24
Area = 547.1136 ft^2

Answer:
[tex]x=15.3[/tex]
Step-by-step explanation:
In right triangles only:
The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)
The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)
The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)
Therefore, we have the following equation:
[tex]\sin 58^{\circ}=\frac{x}{18},\\x=18\sin 58^{\circ}\approx \boxed{15.3}[/tex]
Alternative:
[tex]\cos 32^{\circ}=\frac{x}{18},\\x=18\cos32^{\circ}\approx \boxed{15.3}[/tex]

Which measure of variation is found by placing the data in ascending order and subtracting the lowest value from the highest value?
Answers
Answer:
Range
Step-by-step explanation:
The range of a given set of data is the difference between the largest value and the smallest value in the data. For convenience and ease in the calculation, it is advisable to place the data in ascending order.
For example, given the following set of data:
4,9,5,6,2
To find the range;
=> First arrange the data in ascending order
2,4,5,6,9
=> Find the smallest and largest numbers and then find their difference.
Since the data has been arranged, it is obvious to see that the smallest number is 2 and the largest number is 9.
Therefore the;
range = 9 -2 = 7

Frankie bought a new computer. He made an initial payment of 50$ to the store, and he will pay 30$ each month until the computer is paid off. Which equation represents the relationship between m, the number of monthly payments Franke has made, and t, the total amount that Frankie has paid the store?
A. t=50m+30
B. t = 30m - 50
C. t = 50m - 30
D. t = 30m + 50
Answers
Answer:
Inital payment is 50 so no matter what there is going to be a plus 50.
Then 30 each month, we use m as a way of representing months.
you put that together and you get 30m+50
Answer:
d: t= 30m +50
Step-by-step explanation:
Frankie is paying $30 each month, meaning multiplication is used (30m). He only makes one initial payment so thats why +50 is there.

How to make a data set with only 5 numbers. And so the mean is 7, the median is 7, and the mode is 5?
Answers
Answer:
5,5,7,8,10
Step-by-step explanation:
mode=5 so that would appear the most so start with 5,5
median=7 that would be the middle number so 7 would be next
when you add 5+5+7=17 now just choose any number to add to 17 and I choose 10 which makes 17+10=27.
mean=7 so that means the total has to be divided by how many numbers you have, which is 5. So the total divided by 5 should equal 7. Since have 27, the number divided by 5 to get 7 is 35. So, add to 27 to get 35 which would be 8.
27+8=35 that is your total. Now divide by 5 to get the mean of 7.

Actually Welcome to the concept of Surface Areas and Volume.
==> Volume of Cylinder = πr^2h

==> 27 = r^2 (3)
==> r^2 = 9
==> r = 3 inch
hence the radius is 3 inches.
