1 & 2 are functions
3 & 4 are not a functions
Answer:
area of circle=pi times radius^2
diameter/2=radius
area of rectangle=length times width
rectanlge-circle=scarf
rectanlge=28 by 15=28*15=420
circle, diameter is 15 so radius is 15/2=7.5
area=pi7.5^2=pi56.25=3.14*56.25=176.625
so
rectangle-circle=420-176.625=243.375 square inches
the area of the scarf is 243.375 square inches
Step-by-step explanation:
Answer: 0, Zero
Step-by-step explanation: all horizontal lines are of the form "y = some number", and the equation "y = some number" always graphs as a horizontal line.
The answer is x=5 or x=1/2.
Circumfrence: pi times diameter
7.9*
circumfrence is approximatley 24.806
area:
a=
*(1/2(d))^2
a= 48.99
