The area of a circle = pi * radius squared. so if the area = 136.45, start by dividing by pi to get about 43.43. this means the radius squared = 43.43. square root both sides to get about 6.59 = radius of the circle. the circumference can be found by multiplying the diameter * pi. since the diameter = the radius * 2, we know the diameter of the circle is 13.18. multiply by pi to find the circumference, which would be about 41.41.
Step-by-step explanation:
At Bob's binders, the unit price = $4.20 ÷ 3
= $1.40
At Pam's Paper Place the unit price = $5.20 ÷ 4 = $1.30
the better buy is at Pam's Paper place
I don't understand. What are the values given? Are they values of an x,y plot?
If you plot them they are a straight line with y =6x - 2.9 but I don't know what you mean by when x=3 and y = 4?
The range of the piecewise function would be from [2,infinity), or the second choice.
Answer:
Perimeter = 180
Area = 1080
Step-by-step explanation:
Perimeter is length of all sides added together. 30+78+72 = 180
Area is the length times the height/2 for a triangle. 30*72/2 = 1080
I hope this helped <3
