Hey there!
We are looking for the circumference of the circle, which is the distance around it. We are given the area, which is the radius squared times pi.
First, we need to undo the area to find our radius.
113.04/3.14=36
We square root this to find the radius.
√36=6
Our radius is six. To find the circumference, we need to multiply the diameter by pi. The diameter is twice the radius.
6*2=12
12*3.14=37.68
Therefore, we will need 37.68 feet of trim to around the edge of the quilt.
I hope this helps!
To convert from a fraction to a percent,
You just need to divide the fractions then multiply the product by 100.
Examples:
1. What is 3/4 in percent?
a. 3/4 = 0.75 x 100 = 75%
b. 45/98 = 0.46 x 100 = 46&
c. 60/100 = 0.6 x 100 = 60%
d. 1/5 = 0.2 x 100 = 20&
e. 6/99 = 0.06 x 100 = 6%
What is the question that you are asking? Do you need to write an equation?
Answer:
mean and range
arrangement before: 24,25,25,26,27
arrangement after: 24,25,25,25,26,27,28
mean before: (27+25+24+26+25)/5 = 25.4
mean after: (27+25+24+26+25+25+28))/5 = 25.7
median before: 25
median after: 25
mode before: 25
mode after: 25
range before: 24 to 27
range after: 24 to 28
hence, the mean and range were affected while the median and mode remained unchanged.
13. 9x^2-36x+36
14. 4x^2+14x+20
Remember area formula for a square is Length times Width.
The area formula for a triangle is 1/2base times height.
